Collectible coins in the United States include a variety of denominations, such as the cent (1 cent or 1c) and half dollar (50 cents or 50c). Proof sets, particularly from significant years like 1986, are sought after by collectors. These sets typically contain specially minted coins that exhibit a higher quality finish and detail, produced for collectors rather than general circulation. Collectible coins can vary in value based on factors such as rarity, condition, demand, and historical significance.
