  1. Why the PMG grader called 70 Gem Unc instead of 70 superd Gem Unc?
  2. Dear: Admin I am looking at the PMG grading scale 69 and 70 mentioned about registration and margins, how do measure them? Also the pinholes effect the grading of the banknotes eg 2 small pinholes, or 4 small pinholes. Looking forwward to hear from the admin. Thank you. Best regards J. Vuong
