Collectors and experts now consider it one of the most valuable dimes in U.S. history.

The 1942/1 Mercury Dime Overdate Error

The Mercury Dime, officially known as the Winged Liberty Head Dime, was produced from 1916 to 1945. In 1942, a striking error occurred at the Philadelphia Mint when a die was mistakenly used after already being punched with a 1941 date. As a result, the “2” was stamped over the faint outline of a “1,” creating what is known as a 1942/1 overdate error. The mistake was not immediately noticed, allowing a limited number of these dimes to enter circulation before the error was corrected.

Why This Coin Is So Valuable

The 1942/1 overdate error is extremely rare and easily identifiable, making it highly desirable for collectors. The overdate is most noticeable under magnification, with parts of the “1” clearly visible beneath the “2.” This coin’s value is boosted by both its historical relevance and the fact that it is a one-year error that only occurred at the Philadelphia Mint. A high-grade version of this error dime recently sold for an astonishing $7.1 million, due to its pristine condition and rarity.

Other Rare Mercury Dimes Worth Watching

In addition to the 1942/1 overdate error, there are a few other Mercury Dimes that fetch high prices among collectors. The 1916-D Mercury Dime, the first-year issue from the Denver Mint, is considered rare because of its low mintage. The 1945 Micro S Dime, with a smaller-than-usual mint mark, is another valuable piece due to its unique variation. Together, these rare Mercury Dimes highlight how even small minting quirks can transform a coin into a coveted treasure.
