Verification of certification numbers on the PCGS Certification Database does not eliminate the risk of buying counterfeit and altered coins. Though uncommon, counterfeiters may also counterfeit PCGS grading inserts using actual certification numbers derived from public sources.
As a general rule, PCGS encourages the purchase of PCGS verified coins from PCGS Authorized Dealers.
