1921

The 1921 Philadelphia Morgan Dollar carries the largest single-year mintage in the series at 44,690,000 pieces, struck after the Pittman Act of April 1918 authorized both the melting of 270 million silver dollars during World War I and a corresponding reissue to maintain Treasury silver-dollar coverage. Production resumed in 1921 using new shallow-relief working hubs prepared by George T. Morgan because the original 1878 hubs had been destroyed during the seventeen-year hiatus. The shallow-relief design produces a flatter portrait, less pronounced hair texture above Liberty's ear, and weaker eagle breast detail than 1878-1904 production. The 1921-P accounts for roughly two-thirds of all 1921 reissue production across the Philadelphia, Denver, and San Francisco mints combined.

Strike quality on 1921-P examples varies widely across the production run, with many pieces showing flat hair detail above Liberty's ear and incomplete eagle breast feathering reflecting the shallow-relief hub design rather than die wear. PCGS, the Professional Coin Grading Service, and NGC certified-population data show the 1921-P abundant through Mint State 65 with steady supply at MS66; MS67 examples are scarce and command meaningful premiums over the standard mint-state grades. The 1921-P circulated heavily through the 1920s and 1930s before slipping into Treasury vault storage, where bag quantities surfaced periodically through the 1962 vault release era and the GSA distributions of the 1970s. Prooflike and deep mirror prooflike designations are uncommon for 1921-P examples.

The 1921 Philadelphia Morgan Dollar is a regular-date entry within the series and remains accessible at MS63 through MS65 for new collectors building a complete 1878-1921 set or seeking entry-level Morgan exposure. Strict registry-set collectors target the MS67 grade level, where price acceleration is steep relative to the standard MS65 baseline. The 1921-P pairs naturally with the 1921-D and 1921-S as the matched reissue-year trio that closes the Morgan series, and with the 1921 Chapman Proof and the 1921 Zerbe Special Strikes as the documented specialty productions of the reissue year.
