Numismatic Value Guide: Discover Your Coin’s True Worth by Grade

Wondering how much your coin might be worth? In the world of numismatics, a coin’s value is influenced by more than just its metal content—factors such as condition, rarity, historical significance, and collector demand all play a crucial role. Even small differences in wear, strike quality, or preservation can have a major impact on market value. Use the grading table below, which ranges from circulated grades (Good, Fine) to top-quality uncirculated coins (Mint State, Proof), to better understand the potential worth of your coin. You might be surprised to learn how a well-preserved example can be worth several times more than a heavily circulated one.
