MINT: Perfect Comic Book. Its cover has full luster, with edges sharp
and pages like new. There are no signs of wear or aging. It is not imperfectly
printed or off-center. "Mint" means just what it says.

NEAR MINT : This is a nearly perfect comic book.  Its cover shows barely
perceptible signs of wear. Its spine is tight, and its cover has only minor
loss of luster and only minor printing defects. Some discoloration is
acceptable in older comics - as are signs of aging.

VERY FINE:  This is a nice comic with beginning signs of wear. There
can be slight creases and wrinkles at the staples, but it is a flat, clean
issue with definite signs of being read a few times. There is some loss
of the original gloss, but it is in general an attractive comic book.

FINE: This comic book's cover is worn but flat and clean with no defacement.
There is usually no cover writing or tape repair. Stress lines around the 
staples and more rounded corners are permitted. It is a good-looking
issue at first glance.

VERY GOOD: Most of the gloss is gone from this well-read issue.
There are minor markings, discoloration, and/or heavy stress lines
around the staples and spine. The cover may have minor tears and/or
corner creases, and spine-rolling is permissible.

GOOD: This is a worn comic book with nothing missing. Creases,
minor tears, rolled spine, and cover flaking are permissible. Older
Golden Age comic books often come in this condition.

FAIR: This comic book has multiple problems but is structurally intact.
Copies may be soiled, slightly damaged cover, a badly rolled spine,
cover flaking, corners gone, and tears. Tape may be present and is
always considered a defect.

POOR: This issue is damaged and generally considered unsuitable for
collecting. While the copy may still contain some readable stories, 
major defects get in the way. Copies may be in the process of
disintegrating and may do so with even light handling.
