Known officially as Winged Liberty Head dimes, these coins showcase a stunning depiction of Lady Liberty wearing a winged cap, a powerful symbol of freedom of thought. Over the years, certain rare editions of these dimes have become prized collectibles, fetching extraordinary values due to their rarity, historical significance, and unique minting errors.
Here’s a closer look at the most valuable Mercury dimes, including some worth up to $500,000.
1916-D Mercury Dime
The 1916-D Mercury Dime is the crown jewel of the series. Minted in Denver, only 264,000 coins were produced, making it the rarest Mercury dime. Uncirculated versions in excellent condition are especially valuable, with prices ranging from $15,000 to $500,000.
1921 Mercury Dime
Minted during a period of economic downturn, the 1921 Mercury Dime had a very low production run. Its scarcity, combined with its historical context, makes it a highly sought-after coin. Values can range from $3,000 to $30,000 depending on condition.
1921-D Mercury Dime
Also minted during the 1921 recession, the 1921-D Mercury Dime was produced in Denver with fewer than 1.2 million coins. Its rarity and high demand among collectors result in prices from $5,000 to $20,000 for well-preserved examples.
1931-S Mercury Dime
This San Francisco-minted coin was struck during the Great Depression, with limited production due to economic challenges. The 1931-S Mercury Dime is rare, especially in higher grades, with values ranging from $1,000 to $10,000.
1942/1 Mercury Dime
This famous overdate error occurred when the “1” in 1941 was accidentally stamped over by “2” during minting. Found in the Philadelphia Mint, this error has made the 1942/1 Mercury Dime a collector’s favorite, valued between $4,000 and $30,000.
1942-D 42 Over 41 Mercury Dime
A similar overdate error occurred in the Denver Mint, resulting in the 1942-D 42 Over 41 Mercury Dime. This coin’s unique visual features and scarcity drive its value, often commanding $4,000 to $30,000 in auctions.
1945-S Micro S Mercury Dime
The 1945-S Micro S Mercury Dime stands out for its smaller-than-usual “S” mint mark, a subtle yet fascinating minting variety. Collectors highly value this unique coin, which can fetch between $1,500 and $10,000.
1918/7-D Mercury Dime
Another significant overdate error, the 1918/7-D Mercury Dime, features an “8” stamped over a “7.” Produced in Denver, this rarity commands high prices, ranging from $10,000 to $30,000, particularly in excellent condition.
1931 Mercury Dime Proof
Proof coins are highly polished versions of standard coins, and the 1931 Mercury Dime Proof is no exception. With very few produced, these coins are visually stunning and extremely rare, often achieving premium prices.
