What downgrades a die-cut from NM?
dings: A ding this serious downgrades an otherwise high perfect card to Ex+.
border creases: These are small creases in the border of the
card, usually at thin parts. Any border creases and the grade drops
smudges: A minor smudge on the back lowers the grade of an otherwise pefect card to NM- at best.
A more major smudge would downgrade to EX+ or lower.
curling: A mint card must lay flat on the table. If it
curls that lowers an otherwise perfect card from mint to NM.
I was able to stand this card on its side without support.
popped perfs: Popped perfs are death blows. That lowers
the grade to Vg+ at best.
dirty backs: A back should be clean.
