Coin grading is one of the most important factors influencing a coin’s market value. A higher grade often results in a higher sale price, but what leads to that better grade?

• Lack of wear or marks – Uncirculated or proof coins show little to no signs of wear, making them more desirable.
• Original luster – Coins with their original shine intact tend to receive better grades. Cleaning a coin can reduce its score.
• Sharp details – Clear lines, readable inscriptions, and well-defined images reflect better preservation and boost grading outcomes.
• No alterations – Coins that are untouched and not artificially enhanced maintain grading integrity.
• Proper storage history – Coins kept in protective environments with low humidity are more likely to stay in excellent condition.

If you're unsure about a coin’s grade, a Rare Coin Dealer California can help evaluate it before sending it to an official grading service. This step can save time and money.
