The Susan B. Anthony dollar coin from 1979-S has a noteworthy past. Coin grading firms have designated the first set of coins struck as 1979-S proof type 1. Among collectors, it’s regarded as an “error coin” since the San Francisco Mint used an old die that caused the coin’s S mint mark to appear hazy.


Upon realization, the mint switched to a fresh die, resulting in coins with a clearer S mint mark.
