Collectible coins encompass a wide range of types, including numismatic coins, ancient coins, commemorative issues, and modern variants like elongated coins. In the United States, collectible coins include both currency produced by the U.S. Mint and those that reflect historical events or figures. Elongated coins, which are typically pressed into an oval shape, often feature designs related to attractions or events, making them popular among collectors. The 1933 gold double eagle is a noteworthy example of a highly sought-after coin that was never circulated and has significant historical value. The coinage of Martin Dow, though lesser-known, may feature unique designs or commemorative themes that appeal to specialized collectors.
