Why PMG Grading?

The establishment of PMG followed the incredible impact that third-party grading had on the coin collecting hobby. The same problems that plagued coin collectors prior to third-party coin grading affected collectors of paper money—without third-party grading, it was easy for sellers to overstate a note’s grade and many counterfeit and altered notes were unwittingly purchased as genuine.

In 2005 PMG was established to provide a fully independent opinion of a note’s authenticity and grade. PMG employs more than 20 full-time note graders as well as outside consultants. To ensure impartiality, PMG and its full-time graders do not buy and sell notes commercially, and strict procedures are in place to prevent consultants from influencing the grades assigned to their own submissions. The combined expertise of the PMG grading team results in unparalleledsuperior accuracy and consistency. The expert and impartial grades assigned by PMG and backed by the PMG Guarantee give buyers and sellers greater confidence, increase liquidity and result in higher prices realized.

Collectors and dealers around the world have embraced PMG certification and, as a result, PMG has become a leading third-party paper money grading service with more than 10 million notes certified. Collectors and dealers around the world have embraced PMG certification and, as a result, PMG has certified more than 10 million notes.
