Graded coins are coins that have been evaluated and assigned a specific grade based on their condition and quality. This grading process is typically performed by professional grading services, which assess factors such as wear, luster, and overall appearance. The grade helps collectors and investors understand the coin's value and desirability in the market. The grading scale often ranges from 1 to 70, with higher numbers indicating better condition. Graded coins are usually encapsulated in protective holders, which display the grade and provide security against damage. Collectors often seek graded coins to ensure they are investing in quality pieces for their collections.
