1890 Proof

Proof Seated Liberty Quarter delivery for 1890 came in at 590 pieces, the lowest Proof figure of the entire series outside the 510-piece 1877 delivery and second only to the 600-piece 1891 finale. Philadelphia circulation production for 1890 stood at 80,000 business strikes, a noticeable jump from the four- and five-thousand figures of 1886 and 1888 but still well below typical Philadelphia quarter output for the era. The Sherman Silver Purchase Act of July 14, 1890 increased the Treasury's required silver acquisition and effectively retired the Bland-Allison framework, but most of the new bullion still flowed toward dollar production rather than fractional silver. The site mintage of 590 reflects the actual Proof delivery and is correct on the catalog page.

Strike characteristics and authentication diagnostics align with the late-series Proof template. 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 across both sides earns Deep Cameo, written DCAM. The 590-piece delivery means CAM survivors appear at a noticeably lower rate in major-service populations than the 1880 to 1885 cluster, and DCAM coins draw substantial premiums because the pool of original-surface coins is thin. 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 reflects both the small Proof delivery and the position of 1890 as the second-to-last year of the series. Combined PCGS and NGC certified Proof populations across all grades sit in the low hundreds, lower than most of the 1880s and second only to the 1891 finale among late-series Proof scarcities. The buyer base draws from Seated quarter Proof set builders, With Motto type collectors completing a Proof example, and date-run specialists chasing the 1875 to 1891 stretch in its closing years. CAM and DCAM designations carry significant premiums, original cabinet patina outprices rebrightened pieces, and certification through a major grading service is the working baseline.
