1921-S Morgan Silver Dollar. MS-66+ (PCGS). A brilliant and untoned Gem with traces of reflectivity sparkling in the reverse fields. When Morgan dollar production halted in 1904, however, no one anticipated a resumption in coinage, and the Mint had destroyed the hubs in 1910. This forced Chief Engraver George T. Morgan (assisted by John R. Sinnock) to prepare copy hubs based on the 1878 7 Tailfeathers, Reverse of 1878 variety. These copy hubs are easily distinguished from the originals as the design is in much shallower relief and of overall poorer workmanship. Nevertheless, the dies that they produced were duly employed by the Philadelphia, Denver and San Francisco mints to strike immense quantities of 1921-dated Morgan dollars. The present example is one of 21.69 million coins struck at the San Francisco Mint and it ranks as one of the very finest certified by PCGS, making it ideal for an advanced Registry Set.
