AI Appraisal Estimate

This Washington Quarter, dated 1964, is a notable specimen of United States currency, representing the final year of circulation quarters struck in a 90% silver and 10% copper composition. Physically, the coin measures approximately 24.3 mm in diameter and, in its original state, would weigh 6.25 grams. Its color is a bright, metallic silver typical of high-purity silver alloys, though this piece shows signs of light circulations and surface dulling. The obverse side features the iconic left-facing profile of George Washington, originally designed by John Flanagan. Notations include the word 'LIBERTY' arched across the top, the motto 'IN GOD WE TRUST' positioned to the left of the neck, and the date '1964' centered at the bottom. The strike appears standard for the era, with visible hair detail on the portrait, though the plastic coin flip obscures fine luster assessment. Condition-wise, the coin shows minor surface abrasions and contact marks consistent with light handling before being placed in a protective holder. The coin is housed in a cardboard and Mylar 2x2 coin flip, which shows some handwritten notation and stapling, a common mid-20th-century preservation method for numismatists. As a last-year-of-silver issue, it holds significant value both as a piece of history and for its bullion content.

I have examined the 1964 Washington Quarter through the provided imagery and description. This specimen represents the final year of the 90% silver composition prior to the transition to base-metal cladding in 1965. Based on the visible surface abrasions, contact marks on Washington's cheek, and the slight dulling of the luster mentioned, I would grade this coin as 'About Uncirculated' (AU-55 to AU-58). The 1964 issue is the most common of all silver Washington Quarters, with a massive mintage exceeding 560 million from the Philadelphia mint alone, which limits its numismatic premium. The current market value is heavily dictated by the 'melt value' of its 0.1808 troy ounces of pure silver. While it retains some collector interest as a final-year silver issue, it lacks the rarity or high-grade 'Mint State' qualities required to command a significant numismatic premium. Comparable circulated 1964 quarters typically trade at a small percentage over their bullion value. A physical inspection would be required to rule out artificial toning or high-quality counterfeits, though the latter is rare for this specific common date. Authenticity through images is limited; I cannot verify the exact weight to the hundredth of a gram or perform a 'ring test' to confirm metallic resonance. For full authentication and a higher-tier valuation, the coin would need to be removed from its Mylar holder for an assessment of the rim and a check for any 'PVC damage' a greenish residue often caused by older plastic flips which could negatively impact its long-term preservation and value.
