the thing about chipcos are that the colors will transfer a bit and get kinda dull, you can see the yellow in the minty chips is more pink in the used chips for the $2s and more blue in the $20s. When you clean them, they get the dirt and grime off, but don't really get much better, just cleaner. There was a chipco cleaning tip where they looked a little better, maybe by scrubbing off a layer of transfer particles, but for these, will not make much difference IMO. I will toss them in the ultrasonic some day to get the crap off the used ones, and that will be all I intend to try for them. I did not buy 1s or 5s, but I assume from the pic the 1s will look a little duller from use, the $5 have the red bleed that is common for chipco. I actually played the 1/2/5 in the casino back in 2005, and they look about the same now as they did then. I did not have any $20s in my stack back then, so cannot comment on them other than they are in good used condition.
