Professional Numismatists Guild

Professional Numismatists Guild

The Professional Numismatists Guild was founded in 1955, due in no small measure to the vision of well-known coin dealer Abe Kosoff. Kosoff and several other coin dealers believed that the hobby of coin collecting would be better served if a professional governing body was organized. After much effort, the Professional Numismatists Guild was established. Its motto, “Knowledge, Integrity, Responsibility” continues to reflect the aims of our not-for-profit organization. By choosing one of our member dealers, you can rest assured that your coin dealer demonstrates these essential qualifications.

For the first decade of its existence, membership in the Professional Numismatists Guild was by invitation, and only a small number of dealers were asked to join. As time passed, the PNG gained stature, experience, and wisdom, and its membership rolls were expanded. Today, the PNG membership is comprised of many of the leading numismatists in the United States and around the world. The depth and breadth of the membership brings a rich diversity to the group and has made such progress possible.

Membership in the Guild

Membership in the Professional Numismatists Guild is not for everyone. To join the PNG, a dealer must have experience in the field, must certify that he or she has significant financial worth, and must be elected by a majority of the present members. All PNG members are subject to the rules and regulations of the Guild, which include an arbitration procedure for resolving disputes between buyers and sellers of numismatic properties.

The Professional Numismatists Guild looks forward to many more years of enhancing the field of numismatics through adherence to strict ethical and professional standards, cooperative projects with the American Numismatic Association including the PNG/ANA Numismatic Trade Show, educational efforts geared to hobbyists, and other programs to benefit what has rightfully been called the world’s greatest hobby. As a serious collector, buyer or seller of coins, currency or precious metals, you should insist that your dealer be a member of the prestigious Professional Numismatists Guild.
