In terms of value, the Susan B. Anthony dollar is worth its face value of one dollar. However, certain varieties or errors can hold a higher value for collectors. For example, coins with double-die errors or other minting errors can be valuable to numismatists.
Since the Susan B. Anthony dollar was not widely accepted by the public and faced criticism due to its resemblance to the quarter dollar, it was discontinued after only a few years. This limited mintage can contribute to its collectibility.
Overall, the 1980 Susan B. Anthony dollar is generally worth its face value of one dollar, although certain varieties or errors may have additional value to collectors.
