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 graders are prohibited from buying and selling notes commercially, which prevents conflicts of interest. 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 the world’s largest third-party paper money grading service with more than 2 million notes certified.

The PMG Grading Scale

PMG grades US and world paper money on the internationally recognized scale of 1 to 70, pioneered by well known numismatist Dr. William Sheldon in 1948. See the PMG Grading Scale >

Some notes have problems such as tears or repairs that result in the note receiving a “Net” grade from PMG. PMG will specifically state the reason(s) why any note is “Net” graded. Only the Genuineness Guarantee portion of the PMG Guarantee applies to notes given a “Net” grade by PMG.
