M - Mint (CD has essentially no flaws - I rarely ever grade CD's at this level since you can always find flaws if you want to inspect close enough - artwork can regularly fall into this category). NM - Near Mint (CD has no readily noticeable flaws upon first glance but may have very minor flaws upon closer inspection - CD is free of readily noticeable scratches/marks - artwork is free of noticeable creases/indentations but may have very minor wear that doesn't stand out).
