Large operation in business since 1984 that grades coins, currency, memorabilia,
sports cards, and books.
Ranked "unacceptable" in a 2002 survey of PNG (Professional Numismatists
Guild) and ICTA (Industry Council for Tangible Assets) members in terms of grading accuracy and ability to detect
altered, repaired, damaged, cleaned, and counterfeit coins.
Rated the most consistent coin grading service of eight major services
(others were PCGS, NGC, ANACS, ICG, SEGS, PCI, and NTC) in a 2003 study by Coin World.
ACG has its supporters. According to one published numismatic writer,
"Alan Hager [ACG founder] has built a profitable business by supplying to people something they want at a
price they are willing to pay. That is in and of itself the noblest human endeavor."
