John,
It has helped me when coming to trading as I can see if I already have the chip without going through each and everyone of them, also if the one I have is damaged, maybe I can get a chip in better conditon. There is 1 thing I should have done though after I catalog a bunch,I should have scanned a page of the ones that were entered, this way I could take it with me when I go to chip shows to see if I already have it.Keeping my duplicates down and you know how men are more visual.
Later,
Greg
