Collectible coins, particularly those from the United States, often include state and territorial quarters, part of the 50 State Quarters program launched in 1999. Each quarter features a unique design representing a U.S. state or territory, with the final release in 2009. Quarters minted in Denver are distinguished by a "D" mintmark, which signifies production at the Denver Mint. The 25-cent coins are sought after by numismatists for their historical significance, design variations, and potential rarity, particularly in uncirculated or proof conditions.
