FO, the CC scale is as follows: CC1 = pristine (1-2 of 100 similar), CC2 = slight use, CC3= significant use, CC4= heavy use, but no abuse, and skillful restoration (maybe), CC5 = 5 major repair or restoration, CC6,7,& 8 are descending condition, and CC9 is wall hanger level.

It is a bit subjective, but manageably so. Or, so far.
