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.
