Baseball Cards by Egantx7

In the most common system used for rating baseball cards, the highest three grades are near mint-to-mint (NM-MT), mint (MT), and "BLANK mint" (also called a "10") which describes cards lacking any staining or imperfection in printing, perfect corners, a surface gloss, and an almost perfectly centered front. This system is used by grading service PSA, and is also used on e-bay when grading cards (hint: if you ever remember seeing Don West on his cable infomercials, he repeated this phrase more than a few times). What is this single word which modifies "mint" to describe the highest condition of card.
