Collectible coins include a variety of types, such as commemorative, bullion, and proof coins. In the United States, the 1-cent (penny) and 50-cent (half dollar) coins are popular among collectors. Proof sets, including those from 1989, are specially minted coins known for their high-quality finish and are typically sold in a set, often featuring uncirculated versions of coins from that year. These sets are sought after by collectors for their aesthetic appeal and limited production.
