2025-S Stacey Park Milbern, Silver Proof

The silver proof rendition of the Stacey Park Milbern quarter pairs a closing program tribute with a premium .999 fine silver composition restricted to United States Mint subscription customers. Milbern was a Korean American disability justice organizer who lived from 1987 to 2020, making her one of the youngest figures recognized anywhere across the four-year American Women Quarters Program that Public Law 116-330 authorized in January 2021. Her co-founding of the Disability Justice Culture Club in Oakland, her policy work at the federal level, and her central role in shaping early pandemic-era mutual aid networks placed her at the center of a generation of organizers redefining American activism. The 380,000 mintage of this silver proof reflects the limited audience for the silver proof set product, which carries a premium over the clad set and appeals to type collectors and topical specialists alike.

The reverse, prepared by an Artistic Infusion Program designer per the United States Mint press release, features Milbern alongside imagery connected to disability solidarity. The obverse preserves Laura Gardin Fraser's 1932 Washington bust. Specifications differ meaningfully from the clad proof: the silver version weighs 6.343 grams, retains the 24.3 millimeter diameter, and is struck in .999 fine silver with a reeded edge. Authentication begins with the weight standard, since the .676 gram differential from clad pieces is detectable on any jeweler's scale. The S mintmark should appear sharply above the date, devices should carry deep frosted relief against mirrored fields, and edge examination should show solid silver coloration rather than the copper core visible on clad strikes.

Top-tier PR-70 Deep Cameo grades from Professional Coin Grading Service (PCGS) and Numismatic Guaranty Company (NGC) trade at multiples of issue price for registry buyers. Original Mint silver proof set packaging adds provenance for the highest-grade examples, and bullion-aware buyers value the .999 fine silver content as a price floor beyond the numismatic premium.
