PMG Grading Process
PMG uses a proven, multi-step process that ensures the accuracy, consistency and integrity of its authentication and grading. Here, you can explore the key stages that each note passes though.
All submissions to PMG in Hong Kong are handled by NGC Hong Kong Ltd. (NGC Hong Kong), its Hong Kong affiliate.
When a submission is received, it is opened by trained PMG staff under security cameras and immediately checked against the submission paperwork. The submission is then entered into PMG’s proprietary tracking system with a unique submission number. If requested by the submitter, the submission is shipped (with insurance) to PMG headquarters for authentication, grading and encapsulation. Alternatively, the submitter can request that their submission be held for the next PMG on-site grading event.
Verification and Research
Each note gets a more detailed review to confirm that its description matches the information provided by the submitter. A unique ID and barcode is assigned to track the note throughout the PMG grading process. Most notes are attributed to a reference catalog (such as Friedberg or Pick) by a researcher. At this stage, the note is separated from the submission paperwork so that PMG’s graders don’t know the submitter’s identity, helping to ensure complete impartiality.
Each note is stored in PMG’s vault until it is ready to be reviewed for authenticity. If the note is determined to be genuine, it will be graded according to the industry-standard PMG Grading Scale. If the note is determined to be counterfeit or altered, it will not be graded.
Before grading, a note that was submitted for Variety or Pedigree attribution is examined by specialized numismatists. The note is compared against published references and other materials to determine whether it qualifies as a particular variety of pedigree. If it does, the appropriate descriptions and/or catalog numbers are added to its record.
Grading is a team effort, with multiple PMG professionals examining every note to ensure accuracy and consistency. PMG’s graders enter a grade for each note into PMG’s computer system. A consensus is then reached on the final grade of the note.
The note is carefully inserted into a high-quality holder along with a secure and attractive label that bears the note's PMG grade, description and unique certification number. Securely sealed on all sides, the PMG holder provides superior optics and preservation for notes.
A Quality Control specialist carefully inspects the note, PMG label and PMG holder. All of the certification details are reviewed for accuracy and the holder is checked for any defects or contaminants.

Packaging and Return
Finally, the notes are individually counted, barcode-scanned and checked against the original submission form. Notes are then securely packaged in a sturdy cardboard box. If the submission was shipped to PMG headquarters, it will now be shipped (with insurance) back to the local office. The PMG-certified notes are now ready to be returned to the submitter.
