One such coin, a 1975 Roosevelt Dime, recently made history by fetching an astonishing $506,250 at an online auction. Originally worth just ten cents, this dime’s incredible rarity has cemented its place as a prized gem in the world of numismatics.

What Makes This 1975 Dime So Special?

The key to this dime’s extraordinary value lies in a rare minting error. Known as the 1975 No-S Roosevelt Dime, it is missing the “S” mint mark that would typically indicate it was produced at the San Francisco Mint.

Why the 1975 No-S Dime Is a Collector’s Dream

At first glance, the 1975 No-S Roosevelt Dime may look like any ordinary coin from the era. However, what makes it extraordinary is the absence of the “S” mint mark, a detail that typically identifies coins struck at the San Francisco Mint.

Only two examples of this rare minting error are known to exist, making it one of the most elusive and desirable coins among collectors. Its extreme scarcity has propelled its value far beyond its modest ten-cent origin.

How the “S” Mint Mark Disappeared

To understand the importance of this error, it’s essential to recognize the role of mint marks. The U.S. Mint uses these marks to indicate a coin’s place of origin:

  • D for Denver
  • P for Philadelphia
  • S for San Francisco
  • W for West Point

In 1975, the San Francisco Mint produced more than 2.8 million proof sets for collectors. These coins undergo a meticulous minting process to ensure their sharp details and mirror-like finishes. However, among the millions struck, two dimes were mistakenly produced without the “S” mint mark. This error was only discovered after the proof sets were released, securing the No-S Dime’s place in coin-collecting history.

From Family Heirloom to Auction Record-Breaker

One of the two known 1975 No-S Dimes carries an incredible backstory. It was originally purchased in 1978 for $18,200—already a substantial sum at the time. The coin was then carefully stored in a bank vault for over four decades as a family heirloom.

After the passing of the original owner, the dime was inherited by his sisters, who decided to sell it. In October 2023, it hit the auction block and shattered previous records, selling for an unprecedented $506,250. For the family, this wasn’t just a rare coin; it was a life-changing asset that showcased the immense value hidden in numismatic treasures.
