What does GSA silver mean?

Answer 1

GSA is an acronym for General Services Administration. Established in 1949, the General Services Administration, an independent agency of the United States government, was created to help manage and support the basic functioning of federal agencies.

"GSA Silver" is referred to silver dollar coins dispersed by the GSA in a series of sales limited to U.S. citizens beginning in 1972. The coins originally were discovered in the U.S. Treasury vaults in bags containing millions of these coins which had been undisturbed since the early 1900's. The sale of these silver coins made collecting Morgan Silver Dollars and Carson City Silver Dollars very popular.
