Report Category # - Quick Question in Newbie Note Collecting Questions Posted March 13, 2020 Hello, I am just getting back into paper money collecting. For the first time, I am planning to submit some notes to PMG for grading. This question has probably been asked many times. I apologize for being redundant but my question is, as required on the submission form,.....what is the category # for a note and where can I find it? Does category mean "Silver Certificate" for example, and if so what is the associated number? Thank you.
