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.
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.
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.
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.
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.
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.

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.
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.
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.
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.
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.
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.
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.

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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
