Collectible coins, particularly U.S. quarters, include specific types and historical issues that attract numismatic interest. The early quarters, minted prior to the 20th century, are notable for their limited mintage and distinctive designs. The 1806 quarter, for instance, is part of the Draped Bust series and is characterized by its unique obverse and reverse features, representing the artistry of early American coinage. Collectors often seek these coins for their historical significance, rarity, and aesthetic appeal.
