Collector's Acceptance Corporation (CAC) :Due to today’s selective collector/dealer, an ever increasing number of certified coins on the market are considered low end for their grade. CAC holds coins to a higher standard according to their information. CAC will verify previously graded coins and award the sticker only to those coins that meet the standard for today’s sophisticated buyer. The CAC sticker means:


• Verified. The coin has been verified as meeting the standard for strict quality within its grade.

• Guaranteed. CAC stands behind their verification by making markets in most actively traded coins.


CAC was founded by leading members of the numismatic community, including John Albanese, a respected authority on coin grading and the rare coin market.
