If you want to understand the true value of your coin collection, grading is where it starts. Coin grading is the process of evaluating a coin’s physical condition—and even small differences in grade can mean the difference between a modest offer and a major payout.
Coin grading assesses a coin’s condition, including its wear, detail, and overall preservation. The most common grading scale ranges from Poor (P-1) to Mint State (MS-70). While a lower-grade coin may still hold value due to rarity or metal content, higher-grade coins – especially uncirculated examples – can command significantly more on the open market.
Condition is everything in numismatics. Consider this example:
That’s the power of grading. Collectors and buyers are willing to pay a premium for coins with minimal wear, strong luster, and sharp detail.
