1891 Proof

The 1891 Morgan Dollar Proof represents the fourteenth-year Mint-produced proof entry for the series, struck at the Philadelphia Mint under formal Mint Director proof procedures with a documented mintage of 650 pieces per the Mint Director's annual report. The 1891 Proof carries the standard Reverse of 1879 hub configuration with the rounded eagle breast and slanted arrow feathers that define Morgan Dollar reverses from 1879 forward. The 650-piece original mintage is the second-lowest of the 1879-1904 P-mint proof sequence after the 590-piece 1890 figure, reflecting the second year of the Sherman Silver Purchase Act era when Treasury silver buying drove sharply expanded business-strike production at Philadelphia, New Orleans, San Francisco, and Carson City.

Authentication of an 1891 Proof requires careful examination of the strike quality, mirrored field character, and surface preservation under five to ten power magnification. The 1891 Proof shows fully struck Liberty hair detail, complete eagle feather definition, and deep mirror fields that distinguish formal proof production from business-strike prooflike examples. PCGS, the Professional Coin Grading Service, and NGC apply standard proof grading conventions across the 1879-1904 Morgan proof sequence. Cameo designations stay uncommon for 1891 Proof examples, reflecting the brilliant rather than frosted device finish typical of early Morgan proof production. The small original mintage produces a tight certified population concentrated in Proof-62 through Proof-64.

The 1891 Proof is a regular-classification proof entry on this site under the standard catalog convention for Morgan proofs, with the 650-piece mintage and the standard proof status reflected in the prose rather than the badge tier. The 1891 Proof pairs with the broader 1879 through 1904 P-mint proof sequence as the matched original-series proof production set, distinct from the three 1878 reverse-subtype proofs and the 1921 Chapman Proof that close the series. Auction records for confirmed examples reflect the second-smallest 1879-1904 P-mint proof mintage and trade at firm premiums in higher Cameo grades.
