What is CAC grading?

CAC grading refers to the evaluation process conducted by the Certified Acceptance Corporation (CAC) for coins that have already been graded by major coin grading services like PCGS or NGC. CAC reviews these coins and, if they meet their strict standards for quality within the grade, places a green or gold sticker on the holder to indicate approval. This sticker adds an extra layer of assurance for buyers and collectors that the coin is solid or high-end for its assigned grade. Coins with CAC stickers often command higher prices in the market because they are seen as premium quality examples.
