What is CAC?
Whether you're a novice or advanced collector, you know that quality is what determines the value of a rare coin. However, within any certified coin grade, not all coins are “solid” quality coins. Now there's an easy way to identify coins that are solid for the grade —a CAC verification sticker. CAC was founded by leading members of the numismatic community who recognize the need for a higher level of grading. With CAC, prices for the solid quality coins can be untethered from the lesser quality counterparts.
A CAC sticker means:

When you see the CAC sticker, you can be confident that the coin has been verified to meet strict CAC quality standards. CAC is an active bidder/ market–maker on many CAC–verified coins. In fact, CAC has purchased over $250 million worth of CAC verified coins.
Why CAC?
Because confidence in a coin's quality is priceless. The CAC sticker speaks for itself. A recent market study confirmed that CAC-stickered coins sell for higher prices, on average, than those same–grade encapsulated coins that are not CAC–approved. And the higher the grade, the higher the premium.
