NEAR MINT-

 Tears: One up to 1/4".
Corner Bends: Only if barely noticeable.
Spine Stress: A few very fine spine stress lines are allowable in this grade.
Staples: Only very minor wear or stress tears allowed.
Tape: No tape of any kind allowed in this grade.
Writing: Only arrival dates on front cover, or very small interior (or back cover) notes, such as a person's name, or price are allowed.
Water Damage: Only the very lightest of humidity yellowing (foxing) would be allowed in this grade. Absolutely no water stains.
Browning: Only very slight browning is allowed in this grade, but dust shadow lines (if small) are acceptable.
Rubber stamps: Neatly placed date stamps are allowed.
Missing Pieces: A very tiny front cover piece up to (1/16" square) or a slightly larger back cover piece (1/8" square) are allowed to be missing on an otherwise beautiful copy.
Folds: It is not unusual for comics in this grade to have some very small corner folds.
Fingerprints: Only one, or at most two, barely noticeable fingerprints allowed. 

EXCELLENT-

They will all have some sort of slight flaw that, in some way, detracts from their overall appearance. Comics in Excellent condition are still considered by most collectors as "investment-grade" books. 
Tears: One tear up to 1/2"only.
Corner Bends:  This flaw is usually the result of a shipping box containing comics being dented on the corner while in transit. 
Spine Stress: Many comics in this grade have spine stress marks. These are usually the result of comics having been in "spinner" racks. Those are the racks you see in grocery stores. Non-collectors often bend over comics to see what is behind them, thus causing stress lines on the cover that can be quite noticeable. If they are not too bad.
Staples: a little wear around the staples, but no rust, no loose centerfold, no major tearing.
Writing: Only very neat, very small writing would be allowed. An example would be if someone penciled a small price on the inside first page of an otherwise excellent comic. That's not a big deal. But grease pencil or names on the cover are verboten.
Rubber Stamps: On the front cover only, a neatly placed international price stamp would be allowed. And this only if the comic were otherwise flawless. 
Tape: No tape is allowed in the Excellent condition category.
Pieces Missing: Only if less than 1/8" square.
Fingerprints: Only when very minor and not ugly. Comics with solid color covers, such as white or black, can be particularly effected by fingerprints. Too many noticeable fingerprints downgrade a comic.
Water stains: No water tains are allowed.
Browning: Light browning is allowed both on the covers and the interior of the comic. But absolutely no brittleness must be present.
Folds: slight corners.
 Spine Rolling: Not allowed except if very minor.
Off-Center Printing: Slight printing deviance is allowable if otherwise very nice.
Cover Scuffing: A small amount of scuffing is allowed and is rather common on comics with dark covers. But it cannot be excessive.

GOOD-

The most common grade for comics that are from the 1970's and early 1980's. These comics have been read. Often, quite a lot. They show considerable wear and have many flaws. But they are firm, tight comic books. They are not significantly damaged in any way and are still a nice collectible. Except for very rare material, however, they are not considered "investment-grade." 
Tears: Several minor tears, or one major tear are allowed.
Corner Bends: Allowed.
Spine Stress: Usually evident, and always allowed, unless the entire comic has been bent in half.
Staples: Lots of wear is allowed, but not any actual tearing. Staples must be attached both at the outside and the centerfold. A minor bit of rust is allowed, but not if it stains the cover or interior pages.
Writing: Small, neat writing is allowed on either cover or the interior. Scribbling, large grease pencil, magic marker, or any other significantly offensive writing is not allowed. Allowable writing includes a person's name, a small price, but it must be done very neatly.
 Tape: minimal.
Pieces Missing: Slight edge damage is allowed.
Fingerprints: Allowed unless they include some external material. 
Water stains: A single small (very small!) droplet is allowable. 
Browning: Almost all comics in this category that are more than ten years old will have some discoloration.
Folds: Almost all the comics in this category will have some cover folds.
Spine Roll: Allowed if it's not excessive.
Off-Center Printing: Allowed.
Cover Scuffing: Allowed.
 

FAIR-

These comics are primarily for reading. 
Tears: Usually lots of small ones. Everything is allowed except the cover being torn completely in half horizontally.  
Spine Stress: Spine can actually be torn up to 1/4" into comic.
Staples: Cover and/or centerfold can be loose. Rust is allowed.
Writing: All writing is allowed except for excessive magic marker or writing on the story pages in such a way as to detract from the story.
Rubber Stamps: Allowed unless they are excessive in quantity.
Tape: Allowed.
Fingerprints: Allowed.
Water stains: Allowed.
Browning: Usually evident. The comic may also be losing some of its suppleness and trying to get slightly brittle. But it can't actually be flaking.
Folds: Lots of them. Including subscription folds.
Spine Rolls: Allowed.
Off-Center Printing: Allowed.
Cover Scuffing: Allowed.

POOR-

Comics in Poor condition have complete stories, but may be excessively taped, torn, water-damaged, brittle, have half the front cover or all the back cover missing, interior non-story pages missing, interior coupons clipped, excessive writing, or excessive rubber stamps. The one point in their favor is that their stories are complete. If you just want to own an old comic, and don't care that it's basically a rag, this is your category.
