A coin dealer would never accept return of a coin that you had cleaned

OK, fine by me.

In my book, the seller should probably send Ruben a couple of bucks for the bang-up cleaning job!

I am grateful that casino chips are NOT coins. We don't slab 'em, we get to play with 'em, we tend NOT to speculate like coin collectors do, etc. Any I honestly believed that if you polled every chipper, a substantial majority would find no fault with cleaning a chip. I used to think that I should not clean my "better" chips, but after thinking long and hard about it, I came to the conclusion that I get more joy out of looking at a spiffed-up classic old Vegas chip than I would out of the potential of a few extra bucks made down the line if i decided to resell the chip. I think that for every buyer who would be turned off by the cleaned chip, at least one other would be turned on by it.

One other important point.....coins typically do not acquire the grunge that chips (from some certain casinos lol) tend to. We have all seen chips that could easily be labeled "BIOHAZARD". Coins can get funky, but rarely do you see a coin THAT bad.

The "cleaning hurts value" school of thought in chipping, in my book, is way overrated. I have seen too many sales examples of cleaned chips outselling dirty ones to even consider it anymore.
