Collectible coins encompass a diverse range of items that attract collectors for their historical significance, rarity, artistic value, or unique characteristics. Elongated coins, specifically, are created by flattening and imprinting designs onto a standard coin, often produced by machines at tourist attractions and venues. The 1909 Martin-Dow elongated coin may refer to a specific piece from that era, though details regarding its design and rarity might not be well-documented. Such coins can be classified as part of the "Other Varied" category due to their unconventional nature compared to standard numismatic items.
