1891

The 1891 half dollar is the final entry in the Seated Liberty series, which began in 1839 under Christian Gobrecht and closed with a single Philadelphia issue. Calendar-year business-strike output came to 200,000 pieces, a dramatic return to working production levels after a twelve-year stretch in which annual Philadelphia mintages had run between 4,400 and 12,001. Two forces drove the increase. The Sherman Silver Purchase Act of July 1890 obligated the Treasury to acquire roughly 4.5 million ounces of silver each month, expanding the metal available to the coinage operation after the constrained Bland-Allison years. At the same time, the Mint had already settled on the changeover to Charles E. Barber's new design for the dime, quarter, and half dollar beginning in 1892, and there was operational sense in striking a final supply of halves under the outgoing dies before retooling.

Strike quality on the 1891 runs ahead of the late-1880s issues because the dies were used at production rates rather than babied for collector preservation. Look for full head detail on Liberty, complete shield lines, and crisp claw and arrow definition on the eagle, with the date and stars rendered sharply by fresh working dies. Surfaces typically show normal cartwheel luster rather than the prooflike character that marks 1879 through 1890 survivors, a useful authentication cue when paired with the date logotype, which sets the final 1 squarely on the rock with rounded upper loops on the 8 and 9. The 1891 proof is a separate entry; a business strike under magnification shows radial flow lines rather than the watery mirror and squared wire rims of a proof. Specifications hold at 12.50 grams on .900 fine silver with a 30.6 millimeter reeded edge.

For date collectors the 1891 is most often encountered as the closer of the series and as the Seated half slot in a type set covering U.S. silver designs. Survivorship at higher grades is unusually strong for the era because contemporary collectors recognized the final-year status and pulled examples directly from the Mint, producing a Mint State pool broader than the mintage alone would suggest while circulated coins are correspondingly less common in the marketplace.
