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.
