1901-S Morgan Silver Dollar. MS-66 (PCGS).This is a brilliant and highly lustrous Gem with exceptionally smooth surfaces. A scarce San Francisco Mint Morgan dollar in all grades (probably due to widespread melting of undistributed examples), the 1901-S is also a conditionally challenging issue that can be very difficult to locate any finer than MS-64. Here, then, is a significant bidding opportunity for the advanced collector specializing in this perennially popular silver dollar series.PCGS Population: 33; 8 finer in this category (MS-67 finest).
