Certified Acceptance Corporation

Certified Acceptance Corporation (CAC) is a Far Hills, New Jersey coin certification company started in 2007 by coin dealer John Albanese. The firm evaluates certain U.S. coins already certified by Numismatic Guaranty Corporation (NGC) or Professional Coin Grading Service (PCGS).

Coins which CAC deems solid or high-end for their grades receive green stickers, which usually add premiums ranging from single digit percentages to 92% or more. Coins which are solid or high end for the next grade up are bestowed gold stickers, which on average increase values up to 90% or more of PCGS/NGC coins already graded the next highest grade. CAC buys and sells CAC-certified coins via their affiliated 180-member trading network, Coinplex. As of September 2015, CAC had purchased over $425 million worth of its stickered coins.

CAC has evaluated over 650,000 certified coins with a value of over $2.9 billion. The company has 415 dealer members and 534 collector members. The firm's website maintains a free serial number verification service, which helps deter CAC sticker counterfeiting, and Population Report, which assists in determining coin rarity.

For tiered fees, CAC examines certain numismatically valuable U.S. coins to determine their quality within their assigned grades. Coins which are solid or high-end for their grades will have a green, tamper-evident holographic sticker affixed to their holders. In the unusual event that a coin is found to be high-end for the next highest grade (or even finer), a gold sticker is affixed instead. Coins deemed to be low-end, average, or over-graded receive no sticker at all. CAC accepts most numismatically valuable coins but not modern or bullion coins.

CAC's founder, John Albanese, is a co-founder of PCGS, started in 1986, and founder of NGC, which began in 1987. Grading standards have changed over the years. Because collectors and dealers have gotten more selective, an informal "sub-grade" system has evolved. "A" coins are the best of the grade, "B" coins are "solid", and "C" coins are at the low end of a particular grade based on the Sheldon scale, e.g., MS-65. CAC stickers are intended to standardize this system. "A" and "B" coins receive a green CAC sticker, whereas "C" coins do not.

CAC has 415 dealer members and 534 collector members. The firm has evaluated over 650,000 coin with a market value of over $2.9 billion. CAC-stickered coins almost always fetch premiums, including on eBay and other Internet auctions, and auctions held by the two largest coin auctioneers, Heritage Auctions and Stack's Bowers. Premiums for green sticker coins usually range from single digit percentiles to 92% or more, with gold sticker specimens yielding average premiums of 80% to 90% or more of PCGS/NGC coins already graded the next highest grade.
