Collecting rare coins is a fascinating hobby that blends history, art, and economics. Mint marks, the small letters indicating where a coin was minted, are crucial in determining a coin’s rarity and value.
Some U.S. Mint facilities were short-lived, producing limited coins, which have become highly sought after by collectors today.
