Grading Morgan Dollars (1878-1921) The Morgan Dollar was coined solely as a subsidy for the domestic silver mining industry, and silver certificate notes took their place in daily commerce. Because these coins were not required for general circulation, millions of uncirculated pieces sat idle in Treasury Department vaults or in Federal Reserve banks.
1897 Morgan Dollar. Once considered a rare date, the 1897 Morgan Dollar was released in large numbers during the 1950âs and 1960âs. The mintage of 2,822,000 coins were not often seen during the year of release and even the decades following. The eventual release of the coins provided an ample supply of higher mint state examples for collectors. Similar situations have occurred for numerous other issues of the Morgan Dollar series.
