Thanks again for the replys

I'll leave the chip alone. Was just asking a hypothetical. If I "restored" something i would never try to pass it off as an original. I'm not that type of person. I know some collectables are better off left alone. Wasnt sure if chips were one of them or not. I'm not an avid singles collector. I collect sets of chips, but when I run across interesting singles I usually pick them up.
