US silver dollars designed by George T. Morgan were produced by the millions from 1878-1921 at several mints. In 1892 they were struck at the Philadelphia (no mint mark), Carson City (CC) and New Orleans (O) mints, including a very small number of proofs minted at Philadelphia. They range in value from a slight premium over their silver content of .77344 oz., to more than $100,000, depending on date, mintmark, and condition. What is your specific question
