1987-S United States Constitution 200th Anniversary Proof Silver Dollar

This is a 1987-S Proof Silver Dollar minted by the United States Mint to commemorate the 200th anniversary of the signing of the U.S. Constitution. The coin is composed of 90% silver and 10% copper, with a weight of 26.73 grams and a diameter of 38.1mm. The obverse, designed by Patricia Lewis Verani, features a quill pen, a sheaf of parchment paper, and the words 'WE THE PEOPLE.' The reverse depicts a cross-section of Americans representing different periods of history. This specific specimen is a 'Proof' finish, characterized by its mirrored fields and frosted relief details, indicating it was struck specifically for collectors using polished dies. It is housed in its original government packaging, which consists of a blue velvet-lined presentation case and a protective acrylic capsule. The interior lid features the seal of the Department of the Treasury. The coin appears to be in excellent condition with no visible signs of milk spots, toning, or haze through the capsule. This coin was struck at the San Francisco Mint, as indicated by the 'S' mint mark. It is a classic example of late 20th-century American commemorative numismatics, valued for both its silver content and its historical significance.

I have carefully examined the provided images and descriptions of the 1987-S United States Constitution 200th Anniversary Proof Silver Dollar. The coin displays the characteristic 'S' mint mark from San Francisco and possesses the high-contrast frosted motifs and mirrored fields expected of a 'Proof' strike. Visually, the specimen appears well-preserved within its original Department of the Treasury velvet-lined presentation case. The lack of visible oxidation, milk spots, or haze through the acrylic capsule suggests it has been stored in a climate-controlled environment, which is critical for maintaining its numismatic premium. The market for modern U.S. commemoratives is highly liquid but dictated by high mintage numbers. With over 2.7 million Proofs struck for this series, it is not a rarity. Current value is driven by two factors: the spot price of its 0.7734 troy ounces of silver and the demand from collectors completing 'Commemorative Silver Dollar' sets. While many such coins have been sent for professional grading (e.g., PCGS or NGC), this specimen remains in its original government packaging (OGP), which appeals to traditionalist collectors. Note that this appraisal is based on visual data alone. Full authentication would require a physical inspection to verify weight, diameter, and specific gravity to rule out sophisticated counterfeits. I would also need to examine the coin under 10x magnification outside of the capsule to confirm the absence of hairline scratches or 'wiping' marks that would significantly degrade its value. For insurance purposes, the OGP and any accompanying Certificates of Authenticity should be kept together, as their absence typically reduces the market value by 15-20%.
