1871 Proof

The 1871 Proof is the Philadelphia delivery from the second year of three-mint Seated quarter production, with mintage recorded at approximately 960 pieces. The figure sits just under the 1870 delivery and inside the stable Proof production cadence the Mint maintained through the close of the With Motto subtype in 1872. Carson City struck its second-year 1871-CC quarter at a tiny 10,890-piece circulation figure that quickly became a series Key Date, but Carson City did not produce Proofs, so the entire 1871 Proof story sits at Philadelphia. Circulation production at Philadelphia for the year reached 119,160 quarters, a clean recovery from the late-1860s troughs. The figure shown on the catalog page reflects circulation output for the year; the actual Proof figure is around 960 pieces.

Strike and authentication diagnostics follow the With Motto pattern. Brilliant Proof striking on 1871 dies shows fully mirrored fields, sharp denticles, and squared rims, with Liberty's head, the shield lines, and the eagle's leg feathers all coming up at full strike depth. The reverse should show "IN GOD WE TRUST" on the banner above the eagle in sharp raised letters, and weight should fall near 6.22 grams under the Coinage Act of February 21, 1853 standard. The Philadelphia Proof carries no mintmark, and any mintmark below the eagle on the reverse disqualifies the piece. Cameo contrast, the frosted-devices-against-mirrored-fields appearance designated CAM by PCGS, the Professional Coin Grading Service, and NGC, the Numismatic Guaranty Company, appears with reasonable regularity on the 1871 delivery. Deep Cameo from the year remains scarce and trades at a meaningful multiple over a CAM example at the same numerical grade. Hairlines from old cleaning continue to drive grade compression on the surviving population.

Market position is steady. With Motto type-set builders, Seated quarter Proof date set collectors, and post-Civil War silver Proof specialists draw on the same supply pool, and attractive PR64 to PR66 examples trade at predictable auction levels. Cameo examples step up a tier in price, and Deep Cameo is a stand-alone purchase. Original cabinet toning beats rebrightened surfaces head to head, and certification through a major grading service is the working baseline. The Carson City Key Date for 1871-CC layers cross-collector demand from Seated quarter generalists who pair the Carson piece with the matching Philadelphia Proof to complete the date holding.
