Among the most cherished silver coins in American history, the Mercury dime — officially the Winged Liberty Head dime — combines artistic beauty with a rich array of collector interest. Within the Mercury dime series (1916-1945), several dates stand out as genuine rarities that command significant premiums. Meanwhile, earlier dime series and even the modern Roosevelt dime have their own notable key dates. At American Gold Buyers, located at 1178 Woodruff Road, Greenville, SC 29607, we evaluate dime collections carefully and purchase key dates from customers across Greenville and Upstate South Carolina.

The Mercury Dime Series (1916–1945)
Sculptor Adolph Weinman designed the Mercury dime, which debuted in 1916. The obverse features a young Liberty wearing a winged Phrygian cap — the “wings” suggested flight of thought, though many observers assumed the figure was the Roman god Mercury, and the name stuck. The reverse shows a fasces (bound bundle of rods with an axe) symbolizing unity, alongside an olive branch symbolizing peace. Every Mercury dime is .900 fine silver, containing 0.07234 troy ounces of pure silver.
The 1916-D: King of Mercury Dimes
The 1916-D Mercury dime holds the distinction of being the lowest-mintage business-strike coin in the entire Mercury dime series. With only 264,000 coins struck at the Denver Mint in the first year of the series, surviving examples are scarce in all grades. Even heavily worn examples in Good (G-4) condition command strong premiums.
The 1916-D is one of the most counterfeited coins in American numismatics. Counterfeiters alter 1916 Philadelphia cents (which are common) by adding a “D” mint mark, or alter 1942-D and other D-mint dimes. For any coin believed to be a genuine 1916-D, authentication by PCGS or NGC is strongly recommended before buying or selling.
Other Key Date Mercury Dimes
1942/41 Overdate
In the haste of wartime production, 1942 Mercury dimes were struck from dies that had not been fully worked over from 1941 dies, creating an overdate variety where the “41” digits show through the “42” under magnification. Both Philadelphia and Denver Mint versions exist (1942/41 and 1942/41-D), and both are highly collectible.
1921 and 1921-D
Low mintage production years during the post-WWI recession. Both Philadelphia and Denver issues had limited mintages and are genuinely scarce in higher grades.
Fully Struck Full Bands (FB)
While not strictly key dates, Mercury dimes with fully separated horizontal bands on the fasces (designated FB by grading services) command significant premiums across virtually every date in the series. Strike quality varies considerably by date and mint.
Key Date Barber Dimes
The Barber dime series (1892-1916) contains several rarities, most notably the 1894-S — with only 24 specimens known, it is one of the rarest and most valuable coins in all of American numismatics. Even common-date Barber dimes in circulated condition have silver content worth noting.
The Roosevelt Dime: One Key Date
The Roosevelt dime (1946-present) is mostly a modern clad series with low collector premiums, but the 1996-W is a notable exception. Struck at the West Point Mint and included only in 1996 Mint Sets (never sold individually), it is the only regular-issue Roosevelt dime with a “W” mint mark and commands a premium over common dates.
