AI Appraisal Estimate

A set of ten United States quarters housed in a rectangular clear plastic and blue-backed display case. The coins are arranged in two vertical columns of five and are visually consistent with the Washington quarter design. The display case features printed vertical text reading 'Last Ten Philadelphia Proof Quarters'. The columns are labeled with dates corresponding to each coin, ranging from 1955 to 1964. Each coin displays a profile of George Washington and the inscriptions 'LIBERTY' and 'IN GOD WE TRUST'. The coinage is attributed to the Philadelphia mint based on the text on the holder, though mint marks are not visible in this orientation and the claim remains unverified without an in-person physical inspection of each coin. The coins appear to have a mirror-like field and frosted devices, a finish that is stylistically consistent with modern proof strikes. Some coins, notably the 1960 and 1961 examples, show darkening or toning around the edges. The clear plastic case appears to have some surface scuffing and minor wear. The user-supplied category is noted as 'Coin', though the item is a curated set within secondary market packaging.

Based on the images provided, I have examined this ten-piece set of Washington quarters housed in a 'Last Ten Philadelphia Proof Quarters' display. Per the user's submission, these are attributed as Philadelphia mint proof strikes dated 1955 through 1964. Visually, the coins exhibit the mirror-like fields and frosted devices characteristic of proof finishes from this era. Based on what I can see, several specimens—specifically the 1960 and 1961 examples—show edge toning, which is a common occurrence in secondary market plastic housing but can affect individual eye appeal. I cannot confirm the silver content or the specific minting status from a photo alone; a physical inspection would be required to verify the absence of mint marks and to weigh the coins to ensure they meet the 90% silver specifications typical of pre-1965 coinage. The valuation assumes these are indeed genuine proof strikes as described. The market for mid-century proof sets is generally stable, driven primarily by the silver bullion value and the numismatic premium for high-grade specimens. This estimate reflects the set's value as a curated collection in aftermarket packaging. If these coins were found to be standard circulation strikes rather than proofs, or if any are silver-plated replicas, the value would decrease significantly to approximately $40–$60, representing the raw silver melt value. To confirm this valuation, an in-person examination by a numismatist is recommended to check for cleaning or surface impairments that are not visible through the scuffed plastic case.
