1891 Proof

Proof Seated Liberty Quarter delivery for 1891 stood at 600 pieces, the final Proof figure for the series and the last Proof Seated quarter ever struck. Beginning in 1892, Charles Barber's Liberty Head Quarter replaced Gobrecht's seated figure as the design standard, ending the run that had carried American silver quarter coinage since 1838. Philadelphia circulation production for 1891 returned to a more typical level at 3,920,000 business strikes, a sharp rebound from the small late-1880s deliveries that signaled Mint preparation for design changeover. The 600-piece Proof delivery is therefore a series-closer rather than another late-program small batch, and collectors who completed the 1858 to 1891 Proof run end the set with this date. The site mintage of 600 reflects the actual Proof delivery and is correct on the catalog page.

Strike characteristics and authentication diagnostics align with the late-series Proof template, with the final-year status adding one collector-relevant note: an 1891 Proof is the most readily available example of the last-year Seated Liberty Quarter, since 1891 business strikes from Philadelphia, New Orleans, and San Francisco all run into the millions. Brilliant Proof striking shows mirrored fields, sharp denticles, and squared rims, with the eagle's shield lines, leg feathers, and the banner motto "IN GOD WE TRUST" all at full strike depth. Cameo contrast, the visual difference between frosted devices and reflective fields, earns a CAM designation from PCGS, the Professional Coin Grading Service, or NGC, the Numismatic Guaranty Company; heavier frost coverage on both sides earns Deep Cameo, written DCAM. The 600-piece delivery makes CAM survivors meaningfully scarce and DCAM coins genuinely rare. Weight should sit near 6.25 grams under the Coinage Act of February 12, 1873 standard. Counterfeit risk stays low because the die-finishing process resists casual replication.

Market position is shaped by final-year demand. Combined PCGS and NGC certified Proof populations across all grades sit in the low hundreds, comparable to 1890 and well below the 1880 to 1885 cluster. The buyer base draws from Seated quarter Proof set builders completing the 1858 to 1891 run, With Motto type collectors choosing 1891 specifically for last-year significance, and design-transition collectors buying both the 1891 Seated quarter and an 1892 Barber quarter as a paired set. CAM and DCAM designations carry premiums, original cabinet patina outprices rebrightened pieces, and certification through a major grading service is the working baseline.
