The PCGS Story

In 1985, a small group of the nation’s leading coin experts recognized that for the rare coin industry to realize its potential, some serious problems needed to be addressed.

The PCGS Guarantee

The PCGS Guarantee of Grade and Authenticity is fundamental to our concept of third-party grading. The cash-back policy ensures the accuracy of the grade assigned to any PCGS coin as long as it remains in its tamper-evident holder.

As the owner of a PCGS-graded coin, the customer will have the benefit of PCGS’s Guarantee of Grading Accuracy and Authenticity and each PCGS Authorized Dealer will accept the grades assigned to the coins by PCGS.
