There is an auction for some chips for home use.

http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=448161462

This auction includes the following disclaimer.

ATTENTION: BASED ON AGREEMENTS WITH THE CASINO CHIP MANUFACTURER and THE STATE OF MICHIGAN GAMING COMMISSION, THESE CHIPS WILL NOT BE SHIPPED TO THE STATE OF MICHIGAN.

Does anyone know anything about these agreements? There must be an interesting story behind this one.
