Rating Signs:

Condition of signs are rated 1 to 10, 10 being the best grade
9.5 to 10-absolutly a mint sign no imperfection (I never give 10)
9 & 9.4-almost perfect, may have a factory flaw or almost no damage, if there is, there will be none in field, only chips will be around the edge, great gloss
8.5 to 8.9-may have minor damage, small chips, and minor wear but has to have good or great gloss
8 to 8.4-has more damage, chips are getting larger or maybe in an important area, still should have good gloss
7.5 to 7.9-chips are still getting larger or more of them, heavier wear in field, gloss is starting to go
6 to 7.4-theses sign have heavy damage, no gloss, small crease, deep scratches
5 or less-This is a judgment call, poor condition all the way around
