It’s hard to imagine a 1981 Susan B. Anthony Dollar—a coin once overlooked and even disliked by the public—being worth millions today. Yet, one version of this small silver coin shocked the numismatic world when it fetched $7.7 million at auction. The secret? A mysterious and rare mint mark error that transformed an ordinary dollar into an American treasure.
What Makes the 1981 Susan B. Anthony Dollar So Special?
At first glance, the 1981 Susan B. Anthony Dollar looks like any other. It’s a small, silver-colored coin featuring the suffragist Susan B. Anthony, the first woman to appear on a circulating U.S. coin. But a rare few struck that year hide an incredible secret—a misplaced or variant mint mark that makes them priceless to collectors.
The History Behind the Coin
The Susan B. Anthony Dollar was introduced in 1979 to replace the Eisenhower dollar. The goal was to create a smaller, more convenient coin for everyday use. But the design was so close in size and color to a quarter that most people rejected it. The series ended after just a few short years, making the 1981 issues among the lowest mintage modern U.S. coins.
The 1981 dollars were produced only for collectors, not for circulation, which already made them somewhat rare. But the discovery of a mint mark anomaly in a small batch changed everything.
The Rare Mint Mark Mystery
The secret lies in a small but critical detail: the “S” mint mark, representing the San Francisco Mint. A handful of 1981 proof dollars were found to have a misplaced or overpunched “S” mark—believed to have been hand-punched incorrectly during production. This created the legendary 1981-S Type 2 Proof Dollar, where the mint mark is sharply defined and differs subtly from the common Type 1.
Collectors soon realized that this variety was far rarer than anyone imagined. And when one surfaced in near-perfect PR70 Deep Cameo condition, it sold for an astonishing $7.7 million—the highest known price for a modern U.S. dollar coin.
Key Differences Between 1981-S Type 1 and Type 2 Proof Dollars
| Feature | 1981-S Type 1 | 1981-S Type 2 (Rare) |
|---|---|---|
| Mint Mark | Blurry “S” with rounded edges | Sharply cut “S” with clear loops |
| Production | Common collector issue | Extremely limited proof strikes |
| Circulation | Not for circulation | Not for circulation |
| Estimated Value | $25–$50 | Up to $7.7 million (top grade) |
Why Collectors Go Crazy for It
What makes this coin so valuable is its combination of rarity, condition, and historical oddity. Mint mark varieties are fascinating to collectors because they tell stories about how coins were made before automated precision took over. Owning a 1981-S Type 2 Susan B. Anthony Dollar is like holding a piece of minting history—one created by human hands, chance, and time.
