Rare dimes are more than everyday currency—they’re gateways to history and highly coveted collectibles. Recently, a seemingly ordinary dime from 1975 shocked the numismatic world when it sold for an incredible $506,250 at auction. This unassuming coin, minted nearly five decades ago, owes its extraordinary value to a small but significant minting error.
A Mysterious Minting Anomaly
The story of this remarkable dime traces back to the San Francisco Mint. Typically, coins minted there bear the iconic “S” mint mark. However, this particular 1975 Roosevelt dime lacks the mark entirely, a rare oversight that makes it one of the most extraordinary coins ever produced. Only two examples of this error are known to exist, solidifying its place as a numismatic treasure.

Why Is This Coin So Special?
The 1975 no-“S” dime owes its immense value to its rarity and the circumstances of its creation. In 1975, the U.S. Mint produced over 2.8 million proof sets, which included six coins struck with highly polished dies for collectors. Of these millions of sets, only two dimes slipped through without the “S” mint mark. This accidental omission turned them into coveted rarities, sparking intrigue among collectors worldwide.
From Vault to Victory
The recently auctioned 1975 no-“S” dime has a fascinating backstory. It was owned by three sisters from Ohio, who inherited it from their late brother. He had purchased the coin in 1978 for $18,200, a hefty sum at the time. Anticipating its future value, the family kept it secured in a bank vault for over 40 years.
Fast forward to October 2023: the dime’s sale shattered expectations, fetching over $506,000. Adjusted for inflation, its original price of $18,200 equates to roughly $90,000 today, but the auction value exceeded this by more than fivefold, proving its status as a numismatic masterpiece.
A Legacy of Record-Breaking Sales
This isn’t the first time a 1975 no-“S” dime has made headlines. The only other known example sold for $456,000 in 2019, setting a high benchmark. Since then, its rarity and allure have only grown, driving up its value among collectors.
Such record-breaking sales highlight the fascinating world of rare coins, where stories of historical significance and unparalleled scarcity intertwine to create unparalleled demand.
