Collectible coins, including elongated coins, are a popular niche within numismatics, which involves the study and collection of currency. Elongated coins are created by rolling or stamping a coin to form an elongated shape, often featuring a design or inscription. In the United States, these coins often commemorate attractions or events and can vary widely in their artistic representations. The reference to Martin Dow in 1904 indicates a specific creator or manufacturer of such coins from that period, though further details may be unclear or unknown regarding the specific context or value of the coins produced.
