The coin in question is a unique 1871 Pattern & Trial Coin from the United States, specifically designed as a 25-cent piece (quarter dollar). It was minted in Philadelphia, though it bears no mint mark, suggesting it was produced at the primary mint of the nation during that era. This coin is categorized as a proof coin, indicating it was struck using polished dies, resulting in a high-quality finish that is often sought after by collectors. While specific details about its designer are not available, the coin is a notable example of mid-19th century numismatic experimentation. It is important to highlight that this particular coin has a mintage of zero, which implies that it was either never released into circulation or perhaps was produced as a trial piece for testing purposes, making it an extraordinary find for collectors interested in patterns and trial coins. Despite having designated measurements for width, height, and diameter that do not reflect traditional coin specifications (indicated as '0.00000000'), it's understood that this reflects either a lack of recorded dimensions or an error in documentation rather than an absence of physical characteristics. The material used is listed simply as "Other," which often includes various compositions not classified as common metals such as silver or copper. Overall, given its rarity, proof quality, and the historical significance of its year and series, this 1871 quarter has significant potential value in the numismatic market, especially for those focused on collecting patterns and trial coins from the United States.
