The 1880 Morgan silver dollar was minted at four U.S. Mint locations: Philadelphia, New Orleans, Carson City, and San Francisco. The coin was produced under the requirements of the Bland-Allison Act of 1878, which mandated the purchase of large amounts of silver for coinage. Despite millions being minted, many ended up in Treasury vaults, as silver dollars were not popular in circulation. The overdates using leftover 1879 dies make the 1880 Morgan silver dollar particularly interesting to numismatists.
