Morgan silver dollars issued between 1878 and 1921 are the most widely collected coins of the late 19th and early 20th centures. They hold great values for coin collectors. Among Morgan dollars, the rarest is the 1895 Philadelphia issue. Only 880 such coins were made, all in mirror-field Proof format. It is estimated that only around 600 of them are left, which makes it a great collection. Today such coin would sell for thousands of dollars.
