How do you grade condition of a AES cart?

I guess it depends on people. I used to grade stuff near mint, excellent, etc... But when selling on ebay, if the item is used, I just say the item is either good/fair/bad, and try to describe all the flaws (hopefully)-Like NeoBomerban I hate it when poeple say it's mint, and you get a Excellent cart in your opinon. Why not just describe everything, or at least provide a picture? Try to make more money, I guess...It also doesn't help that Neo-Geo cart games can have scratches from shipping.

It's kind of nice for the other buyers that Shawn has a grading system in his selling forum.
