Mint Mark Mistakes: How a Missing ‘S’ Turned a Dime into Treasure

The recent auction of a 1975 Roosevelt dime for a staggering $506,250 has sent shockwaves through the numismatic world. This extraordinary sale highlights the immense value that a tiny detail—or its absence—can create. Here’s a closer look at what makes this dime so special and the lessons collectors can learn from this record-breaking event.

Why the 1975 ‘No S’ Roosevelt Dime Is So Valuable

A Rare Mint Error

The 1975 Roosevelt dime is remarkable due to its lack of the ‘S’ mint mark, which typically signifies coins produced at the San Francisco Mint. Out of the 2.84 million proof sets created in 1975, only two dimes emerged without this critical identifier. Such errors are incredibly rare, making these coins highly coveted among collectors.

Historical Significance

This error coin represents one of the most significant modern minting mistakes in U.S. numismatic history. Its rarity, combined with its provenance and condition, has elevated it to legendary status.

The Discovery and Journey of the ‘No S’ Dime

The two known examples of the 1975 ‘No S’ dime were both discovered in California during the late 1970s. Coin dealer F.J. Vollmer acquired both coins in 1978 and 1979.

Early Investment

The first dime was sold for $18,200—a significant amount at the time—to an Ohio collector and his mother. They wisely stored the coin for decades, allowing it to appreciate in value over time.
