Collectible coins encompass a variety of categories, including historical, numismatic, and commemorative pieces. In the United States, iconic examples include the 1 One Dollar coins, which span various designs from different eras, including the Peace Dollar and the Eisenhower Dollar. Early Quarters, such as the Draped Bust and Seated Liberty types, are highly sought after by collectors for their historical significance and artistry. These coins are valued based on factors like rarity, condition, and market demand, often fetching premium prices in the numismatic market.
