Mint errors can turn ordinary coins into extraordinarily valuable collectibles. While dimes are small in size, some of them have become worth thousands—or even hundreds of thousands—due to unique minting mistakes. From missing mintmarks to off-metal strikes, these rare errors have made certain dimes incredibly valuable in the numismatic world. In this article, we’ll explore three dimes that became highly sought after due to secret minting errors and why collectors are willing to pay a fortune for them.
1. 1942/41 Mercury Dime (Overdate Error)
One of the most famous and valuable error dimes is the 1942/41 Mercury Dime, caused by an overdate mistake at the U.S. Mint. This error occurred when a 1942 dime die was mistakenly stamped over a 1941 die, resulting in an overlapping date. The error was not immediately noticed, and a limited number of these dimes entered circulation.
Because of its rarity, this dime is worth thousands of dollars, even in lower grades. In high grades, an uncirculated 1942/41 Mercury Dime can fetch over $25,000 at auction, making it a prized discovery for collectors.
2. 1968 No-S Roosevelt Dime (Missing Mintmark Error)
The 1968 No-S Roosevelt Dime is a proof coin that was mistakenly minted without the “S” mintmark, which should have been present for all proof dimes struck in San Francisco. This error is extremely rare because proof coins are carefully inspected before release, meaning very few of these dimes escaped into circulation.
Due to its rarity, this dime is now worth thousands of dollars. One example sold for over $40,000 at auction, making it one of the most valuable Roosevelt dimes ever discovered. If you have a 1968 proof set, it’s worth checking for this rare error!
3. 1970 No-S Roosevelt Dime (Proof Error Coin)
Similar to the 1968 No-S dime, the 1970 No-S Roosevelt Dime was also a proof coin struck without its intended mintmark. This mistake was extremely rare, as proof coins from San Francisco should always bear an “S” mintmark. However, a small number of 1970 dimes were minted without it, making them a major numismatic rarity.
Because of its scarcity, this error dime has sold for over $25,000 at auction. Collectors and investors eagerly seek out this variety, as it represents a rare mistake in modern U.S. coinage.
Mint errors can transform a regular dime into a highly valuable collector’s item. Whether it’s an overdate mistake or a missing mintmark, these errors add uniqueness and rarity, driving up their value. If you ever come across an old dime in your collection, take a closer look—it might be worth far more than just ten cents!
