MINT (M): No scratches at all on Holo. Basically pack fresh. No imperfections I can see.
(some of my cards may qualify as MINT but I rarely grade them that way myself)
NEAR MINT (NM): Very few light scratches, Holo may have small scratches, Not perfect - will have some minor imperfections - but looks great overall and will be perfect for most collectors.
