This coin is part of the "Elongated Coins - Martin & Dow" series, which falls under the category of novelty or souvenir coins. These elongated coins are crafted using the mint strike production method, and they are not designated with a specific mint mark. The coin is made of copper, characteristic of many such tokens, and features a diameter of 31mm. Notably, this coin does not have a year of issue or a denomination, which is typical for many elongated coins produced primarily for collectors and tourists rather than for circulation. The properties listed indicate that it may not hold a traditional numismatic value like standard currency coins due to its undefined minting metrics, such as weight and mintage, which are reported as zero. It also does not have an edge type specified, which implies a smooth edge likely consistent with flat, elongated coins. As it lacks a specific date and denomination, it is categorized simply as a souvenir or collectible item representing the United States of America, appealing to coin enthusiasts or visitors interested in unique markers of their travels. Overall, while the exact value of this piece may be difficult to ascertain, the charm and historical fun of elongated coins remain significant to collectors and travelers alike.
