These things are worthless, and should NOT be collected. In fact, storing them in the same room with "clay" chips will cause the clay chips to deteriorate into dust within days. I have an ecologically safe disposal system for the dreaded jetons in my basement. If anyone needs me to destroy their jetons safely please mail them to me (at your expense of course) before they damage your homes beyond repair.

Also, casino plaques have the same effects but magnified by 10x, so get rid of those ASAP too!
