Story
In 1980, the San Francisco Mint struck these gem proof sets containing the newly introduced Susan B. Anthony dollar. While over 3.5 million were produced, finding them with pristine ultra-cameo contrast remains a collector favorite.
Maker / Origin
The United States Mint has been producing coins for the nation since 1792. The San Francisco branch (mintmark 'S'), established during the California Gold Rush, took over the exclusive production of collector proof coinage starting in 1968, setting rigorous standards for mirror polish and high-relief strikes.
Condition & Value
Coins appear uncirculated and well-preserved inside the original sealed hard plastic case, showing crisp cameo frosting. The case shows minor exterior shelf scuffs. Intact original cases preserve value.

Market Analysis
Comparable demand stays strongest where maker, originality, and venue confidence line up. Broader examples still trade, but the range tightens quickly when provenance, condition, or selling lane fit is missing.
Value Drivers
- ▲ Strong maker attribution with credible period details
- ▲ Better-than-average condition for the category
- ▲ Broader demand rises when presentation and finish feel intact
Concerns
- ▼ Decorative-only demand limits the ceiling
- ▼ Surface wear or missing provenance can compress the range fast
- ▼ Regional sale lanes often underperform specialist venues
