Collectible coins can include a variety of types such as numismatic coins, proof coins, and commemorative issues. The United States Mint produces coins in various denominations including 1 cent and 50 cents, which can be collected in different conditions such as uncirculated or proof. A proof set, which features coins struck with a special process to produce a high-quality finish, can be especially sought after by collectors. The 1937 coins, minted in Philadelphia, are notable for their design and historical significance, appealing to both novice and experienced collectors.
