The Valuable 1920 Mercury Dime Errors (Complete Guide)

Beyond mint mark and condition, a small number of 1920 Mercury dimes carry minting errors that make them significantly more valuable. The five varieties below — ranging from die-state errors to dramatic planchet mishaps — represent the most sought-after anomalies in this date. Each one is identifiable with basic tools, and knowing what to look for can make a real difference to your bottom line.

1920 Mercury dime Doubled Die Obverse error showing doubling on Liberty portrait and LIBERTY legend
Most Famous

1920 Doubled Die Obverse (DDO)

$45 – $500+

The Doubled Die Obverse (DDO) occurs when the working hub imprints a slightly rotated or offset impression onto the working die during the hubbing process. This mechanical doubling is distinct from post-mint damage and is locked permanently into the die, meaning every coin struck from that die carries the same anomaly.

On the 1920 DDO, the doubling is most apparent on Liberty's eye, cheekbone, and the letters of the LIBERTY legend. Under a 10× loupe you should see a secondary faint outline of these features offset from the primary impression, giving a "ghost" appearance to the portrait details.

Collector demand for well-preserved DDO examples on Mercury dimes is strong because the design's fine portrait features make the doubling especially dramatic. Premium is greatest on coins where the doubling is sharp and clearly visible without magnification — grade and visibility together drive realized prices.

How to Spot It

With a 10× loupe, examine Liberty's eye and the L, I, B of LIBERTY for a secondary offset impression running slightly clockwise or counterclockwise. Genuine hub doubling shows sharp parallel lines, not the mushy smearing of mechanical damage.

Mint Mark

Primarily P (Philadelphia) — no mint mark. Some D and S issues may also show minor hub doubling variants.

Notable

Mercury dime DDOs are catalogued by CONECA and Variety Vista. A clearly visible 1920-P DDO in VF-30 has sold for over $200 at Heritage Auctions; gem examples with dramatic spread can exceed $500.

1920 Mercury dime off-center strike error showing design shifted from center with blank crescent of metal visible
Most Valuable Error

1920 Off-Center Strike

$100 – $1,800+

An off-center strike occurs when the planchet is not properly centered between the dies at the moment of striking. The result is a coin where the design is shifted away from the center, leaving a visible crescent of unstruck blank metal on the opposite side. The percentage of off-center can range from a few percent to nearly the full diameter.

On a 1920 Mercury dime, off-center strikes are dramatically visible: Liberty's portrait drifts toward one side while part of the reverse design is lost beyond the coin's edge. The date must still be visible for maximum collector appeal. A coin struck 20% off-center once realized approximately $1,800 at auction according to multiple sources — one of the stronger realized prices for this type on a Mercury dime.

Value scales sharply with the percentage of off-center shift and whether the date remains legible. Strikes between 30% and 60% off-center with a visible date are considered the sweet spot for collector premiums on Mercury dime errors of this type.

How to Spot It

Lay the coin flat and look for a crescent-shaped blank area on one side opposite a crowded or partially missing design. Even a 5% shift is detectable with the naked eye; 20%+ off-center examples are unmistakable. Verify the date is still readable for maximum value.

Mint Mark

P, D, and S issues — off-center strikes can occur at any mint; not specific to one facility.

Notable

A documented 20% off-center 1920 Mercury dime realized approximately $1,800 at auction, supported by error coin references. Larger percentage off-center examples with visible date push value toward the top of the range; PCGS and NGC both certify off-center strikes.

1920 Mercury dime clipped planchet error showing curved section missing from the coin's outer edge
Best Kept Secret

1920 Clipped Planchet Error

$45 – $400+

A clipped planchet error results from the metal blanking press punching a new planchet from a strip that overlaps a previously punched hole. The outcome is a coin with a curved (or occasionally straight) section cleanly removed from its edge before striking. The clip is a mint-origin error, entirely distinct from post-mint damage.

On a 1920 Mercury dime, a curved clip creates an immediately striking silhouette — the familiar round coin profile is interrupted by a smooth concave arc. Blakesley's Law provides an additional diagnostic: the area of the design directly opposite the clip often shows weakness or missing detail, because the gap in the planchet prevented full metal flow during striking.

Authenticity is key with clipped planchets: only PCGS or NGC grading can definitively confirm mint-origin clips versus edge damage. Confirmed examples with clear Blakesley effect evidence command the strongest premiums, particularly on coins in AU or better condition where the original design surfaces are well preserved.

How to Spot It

Look for a smooth, curved concave arc missing from the coin's edge — not a rough chip or gouge. Then check the design directly opposite the clip with a loupe: if the legend or rim is weakly struck there (Blakesley effect), you likely have a genuine mint error rather than damage.

Mint Mark

P, D, and S issues — clipped planchets arise from the blanking stage before mint-mark assignment; all three facilities produced them.

Notable

Curved clips between 10%–25% of the coin's width bring the strongest premiums. PCGS and NGC both use the designation "Clipped Planchet" on their holder labels. On well-struck AU Mercury dimes with confirmed clips, values regularly exceed $200 at major auction venues.

1920 Mercury dime die break cud error showing raised irregular blob of metal near coin rim caused by broken die
Rarest Type

1920 Die Break (Cud) Error

$50 – $300+

A die break error occurs when a portion of the working die fractures and breaks away during striking. The void left by the missing piece fills with metal from each subsequent planchet, creating a raised, formless blob on the coin's surface. When the break extends to the rim, the result is a "cud" — the most dramatic and collectible die break variety.

On a 1920 Mercury dime, die breaks most often appear near the rim on either the obverse or reverse, though through-design breaks have also been documented. Coins struck later in a given die's lifespan are more likely to show breaks, as die metal fatigues with repeated high-pressure strikes. The cud itself is always raised above the surrounding field.

Value depends on the size and position of the break. A large cud touching or incorporating a design element — such as Liberty's chin or the fasces — commands significantly more than a small rim break. Major cuds on Mercury dimes have dedicated collector followings and are actively traded at CONECA and error coin club shows.

How to Spot It

Look for a raised, irregular blob of metal — not a scratch or depression — anywhere on the coin surface, especially near the rim. The raised area will have no design detail and will feel smooth under a fingertip. A cud at the rim always extends to (and above) the coin's edge.

Mint Mark

P, D, and S — die breaks occur at any mint facility and are not tied to a specific mint mark. However, P-mint examples are more commonly encountered due to the higher mintage of 59,030,000.

Notable

Die breaks on Mercury dimes are catalogued by CONECA's Error Variety Coin Encyclopedia. Large cud examples on 1920 Philadelphia dimes in Fine to XF condition have sold for $125–$300 at Heritage and eBay; PCGS certifies die breaks with explicit notation on the holder.

1920-D Mercury dime repunched mint mark error showing secondary faint D impression beneath the primary mint mark on the reverse
Collector Favorite

1920 Repunched Mint Mark (RPM)

$30 – $200+

The Repunched Mint Mark (RPM) error originates in the die-preparation process. During this era, mint mark punches were applied by hand to each working die individually. If the punch was misaligned or the die shifted between applications, a secondary mint mark impression appeared next to or overlapping the primary one. The result is a coin with two (or more) mint mark impressions at slightly different positions.

On 1920-D and 1920-S Mercury dimes, RPM examples show a faint secondary D or S adjacent to, above, or below the primary mint mark letter. The secondary impression is best seen at 10×–20× magnification on the reverse, in the area to the right of the first E in ONE DIME. The offset can be as subtle as a partial serif or as dramatic as a full secondary letter.

RPMs are catalogued by CONECA and the Cherrypickers' Guide, and known varieties carry specific CONECA designation numbers. Collectors who specialize in Mercury dime varieties actively search for these, making well-documented RPM examples consistently tradeable at premiums above type-coin values even in circulated grades.

How to Spot It

With a 10× loupe, examine the mint mark on the reverse (right of the first E in ONE DIME). Look for a secondary faint serif or partial letter impression offset north, south, east, or west of the primary mint mark. The secondary impression is part of the die — it won't move or polish away.

Mint Mark

D (Denver) and S (San Francisco) issues only — Philadelphia coins have no mint mark and therefore no RPM variety. The 1920-D RPM is more commonly encountered.

Notable

Known 1920-D RPM varieties are listed in the CONECA Repunched Mint Mark File. A boldly doubled 1920-D RPM in XF-45 has sold for over $150 at Heritage; PCGS and NGC certify RPMs with notation. The 1920-S RPM is considerably scarcer due to the lower base mintage of 13,820,000.

1920 Mercury Dime Mintage & Survival Data

Group of three 1920 Mercury dimes from Philadelphia, Denver, and San Francisco mints showing all three mint varieties
Mint Mint Mark Mintage Est. Survivors Survival Rate
Philadelphia None (P) 59,030,000 ~6,000 0.0102%
Denver D 19,171,000 ~7,500 0.0391%
San Francisco S 13,820,000 ~4,000 0.0289%
Total — 1920 Issue 92,021,000 ~17,500 0.019% avg.

📌 Composition & Specifications

Metal: 90% silver, 10% copper  |  Weight: 2.50 grams  |  Diameter: 17.90 mm  |  Edge: Reeded  |  Designer: Adolph Alexander Weinman  |  Series: Mercury (Winged Liberty Head) Dime, 1916–1945  |  Silver content (ASW): ≈0.07234 troy oz.

Despite Philadelphia striking the most coins by far, its survival rate is paradoxically the lowest — circulating 1920-P dimes saw heavy use and were rarely saved. Denver's higher survival rate reflects deliberate collector saving of the lower-mintage issue. San Francisco's scarcity in top grades comes from inconsistent strike quality that left most surviving coins unable to achieve Full Bands certification.

How to Grade Your 1920 Mercury Dime

Grade determines value more than almost any other factor. Use this visual guide and the four condition tiers below to place your coin in the right range before using the calculator above.

1920 Mercury dime grading strip showing four condition tiers: Worn, Circulated, Uncirculated, and Gem side by side
Worn

Good–Fine (G–F)

Heavy wear throughout. Liberty's hair and wing details are flat. Reverse bands on the fasces are entirely gone or visible only as faint traces. Rim may merge with lettering. Date and legends still legible.

Circulated

VF–AU (VF–58)

Moderate to light wear. Hair curls above Liberty's ear show some detail; wing feathers retain partial separation. Reverse bands are worn but visible. In AU, high points show only trace wear with partial luster in protected areas.

Uncirculated

MS60–MS64

No wear anywhere — full mint luster present. Contact marks and bag marks visible, ranging from numerous (MS60) to minimal (MS64). Key diagnostic: luster must flow continuously across Liberty's cheek and the fasces bands with no dullness from handling.

Gem

MS65+ (Gem)

Near-perfect surfaces with brilliant mint luster. Very few, tiny contact marks visible only under magnification. Strong eye appeal. MS66+ examples are exceptional; MS67 1920-P coins are genuinely rare and command four-figure premiums at auction.

💡 Pro Tip: Check the Strike, Not Just the Wear

Many 1920 Mercury dimes — especially San Francisco issues — were weakly struck at the mint. A weakly struck coin will show flat areas on the fasces bands and Liberty's hair even with no circulation wear. Don't confuse mint weakness for wear: look for mint luster still flowing across the flat area. If luster is present, it's a strike issue, not circulation. This distinction matters enormously for the Full Bands designation and for accurate grading.

Where to Sell Your Valuable 1920 Mercury Dime

The right venue depends on your coin's grade and value. A worn circulated example sells fine on eBay; a gem Full Bands coin deserves a major auction house.

🏛️ Heritage Auctions

The premier venue for high-grade and Full Bands examples. Heritage's Mercury dime specialist buyers compete aggressively for gems and key varieties. Best for MS65+ coins and any confirmed error. Expect 10–15% seller's commission but maximum realized price. The 1920-P FB MS67 that brought $9,000 and the 1920-D MS67 at $4,080 both sold here.

📦 eBay

Excellent for circulated to mid-uncirculated examples. View recently sold prices for 1920 Mercury dimes on eBay to calibrate your expectations before listing. PCGS/NGC-certified coins in holders sell faster and at higher prices than raw coins. Circulated 1920-P examples regularly trade in the $6–$35 range; MS62 certified coins bring $90–$130.

🏪 Local Coin Shop

Fast and convenient for circulated coins or small lots. Dealers typically offer 50–70% of retail for common circulated examples. For any coin above AU55 or with Full Bands, get at least two offers before selling locally — dealers may undervalue high-grade pieces without specialty graders on staff.

💬 Reddit r/Coins

The r/coins and r/CRH communities are helpful for identification and initial valuation. For actual sales, r/CoinSales offers peer-to-peer transactions with lower fees than eBay. Best suited for circulated examples in the $10–$100 range; major auction houses still outperform for gems.

🏆 Get It Graded First

If your 1920 dime appears uncirculated or shows potential Full Bands, submit it to PCGS or NGC before selling. Certification costs $30–$80 per coin but can add hundreds or thousands of dollars to the realized price. A raw MS64 1920-D might bring $200; the same coin in a PCGS holder at MS64 routinely brings $240–$280 or more. For Full Bands candidates, certification is essential — no serious buyer will pay Full Bands money for an unslabbed coin.

Frequently Asked Questions — 1920 Mercury Dime

How much is a 1920 Mercury dime worth?

A well-worn 1920 Philadelphia dime starts around $5–$7. In Fine condition expect $10–$25. Uncirculated examples range from $35 to $650+ depending on grade and mint mark. The rarest version — the 1920-S with Full Bands — has reached $72,000 at major auction. The 1920-D Full Bands is also exceptional, with top examples exceeding $10,000. Coin grade and mint mark are the two biggest drivers of value.

What is the Full Bands designation on a 1920 dime?

Full Bands (FB) refers to the four horizontal bands on the fasces on the reverse of the Mercury dime. For the FB designation to be awarded by PCGS or NGC, all four bands must be fully separated and distinct with no interruptions or flat areas. It is a strike quality designation, not a condition grade. On 1920 coins, striking quality varied considerably — making true Full Bands examples relatively rare and significantly more valuable.

What mint marks does the 1920 Mercury dime come in?

The 1920 Mercury dime was struck at three mints: Philadelphia (no mint mark, 59,030,000 minted), Denver (D mint mark, 19,171,000 minted), and San Francisco (S mint mark, 13,820,000 minted). The mint mark appears on the reverse to the right of the first E in ONE DIME. Philadelphia coins have no letter at all. The 1920-S has the smallest mintage and lowest estimated survival count of the three.

Where is the mint mark on a 1920 dime?

Flip the coin to the reverse side. Look to the right of the letters ONE DIME — specifically to the right of the first E in ONE. A small D means the coin was struck at the Denver Mint. A small S means San Francisco. If there is no letter at all, the coin came from the Philadelphia Mint, which did not use a mint mark on this issue. A magnifying glass or 10× loupe makes identification easier on worn examples.

What is the rarest 1920 Mercury dime?

Among regular strikes, the 1920-S with Full Bands is the most valuable. With a mintage of only 13,820,000 and an estimated surviving population of around 4,000 coins, the San Francisco issue is scarce in all grades. Full Bands examples are genuinely rare — inconsistent strike quality at the San Francisco Mint in this era means most 1920-S dimes do not qualify for the FB designation. An MS67 FB 1920-S has sold for $72,000 at auction.

How do I check if my 1920 dime has Full Bands?

Use a 10× loupe and examine the center of the fasces on the reverse. There are four horizontal bands binding the bundle of rods. For Full Bands (FB), each band must be fully separated from the one above and below it with no merging, flat sections, or interruptions across the entire width of the bands. Even partial flatness in the center disqualifies a coin. FB coins are most often found on the 1920-D; the 1920-S FB is the rarest.

What errors exist on the 1920 Mercury dime?

Known 1920 Mercury dime errors include the Doubled Die Obverse (DDO), showing doubling on Liberty's portrait and legends; the Off-Center Strike, where the design is shifted from the coin's center; the Clipped Planchet, where a curved or straight section is missing from the blank; the Die Break (Cud), showing raised irregular blobs of metal from a cracked die; and the Repunched Mint Mark on D and S issues, showing a secondary faint mint mark beneath the primary one.

What does a 1920 Mercury dime look like?

The obverse shows the head of Liberty in profile wearing a winged cap — often mistaken for the Roman god Mercury, hence the coin's popular name. The word LIBERTY arcs along the top, IN GOD WE TRUST is at left, and the date 1920 sits at the bottom. The reverse displays a fasces — a bundle of rods with an axe blade — crossed by an olive branch. The designer was Adolph Alexander Weinman, and the coin is 17.9mm in diameter.

Is a 1920 dime made of silver?

Yes. The 1920 Mercury dime is composed of 90% silver and 10% copper, weighing 2.50 grams with a diameter of 17.90mm. Its actual silver weight (ASW) is approximately 0.07234 troy ounces. At modern silver prices, the melt value of a 1920 dime is generally around $2–$3, though collector value typically exceeds melt value even for the most worn examples. Never melt a 1920 dime without verifying its numismatic value first.

Should I clean my 1920 Mercury dime before selling it?

No — never clean a 1920 Mercury dime. Cleaning removes the coin's original surface texture and patina, permanently destroying mint luster. A cleaned coin will be labeled Details grade by PCGS or NGC, which dramatically reduces its value and makes it essentially unsellable to serious collectors. Even a tarnished or darkly toned 1920 dime in original condition is worth far more than a polished one. Leave all original surfaces intact and let a professional grader evaluate the coin as-is.
