Ebay has a listing for one of my all-time favourite chips:

http://cgi.ebay.com/GOLDEN-GATE-CASINO-LAS-VEGAS-1-00-chip-1970s_W0QQitemZ350291508477QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item518f003cfd

The "coin" in the center looks to be made out of a different material than most of the other C-I-C's..does anyone know if that is true about this chip?

Thanks.
