The coin in question is a $1 (One Dollar) pattern and trial coin from the United States, minted in 1866 at the Philadelphia Mint. This unique specimen is made of copper and features a proof production type, which indicates it was produced with a high level of detail and finish, typically reserved for presentation pieces or collector's items. Fortunately, this coin does not have a mint mark, suggesting it was struck at the main Philadelphia facility, where many iconic coins from American history were produced. Despite its intriguing characteristics, this coin has a recorded mintage of zero, indicating that it was either never released into circulation or is part of a small number of special strikes kept for government records or collectors. Interestingly, the coin's dimensions (width, height, diameter) and weight are not specified, suggesting that technical measurements may not be readily available or applicable in this particular instance. The edge type is also marked as "N/A," which could further imply that the coin may not conform to standard edge characteristics typically found in other issues. The designer of this particular piece remains unspecified, denoting either the anonymity of the artist or a lack of official acknowledgment for this specific pattern. Given its copper composition and the historical significance of the year 1866—post-Civil War America—it connects to a transformative era in U.S. coinage. As a trial or pattern coin, this piece holds considerable value and interest for numismatists and collectors alike, representing a rare opportunity to own a piece of American minting history.
