When "third party" certification services became available in 1986 we were charter members of Professional Coin Grading Service (PCGS) and Numismatic Guaranty Corporation (NGC). We felt at the time it was necessary to have these services available for those clients who were buying high value rarities. In the intervening years we have also served clients who wish to use the American Numismatic Association Coin Service (ANACS) services as well as those who buy non-certified (raw) coins.
