What does CAC mean?
Ian Russell on Sun, Mar 27, 2011 12:14:39 PM
You will notice that certain coins at Greatcollections have a green "bean" sticker on them with the letters CAC.  These coins will also be described as CAC in the heading.

CAC was founded by John Albanese in 2007, as a third-party to grading services. CAC experts examine coins previously certified by either the Professional Coin Grading Service (PCGS) or the Numismatic Guaranty Corporation of America (NGC). CAC then affixes a distinctive green sticker to the holder of each coin which, in its judgment, fully merits the grade that was assigned. Each sticker incorporates a tamper-resistant hologram.
