Brian has a point regarding the $5! Here is a link for the same chip, not from the dig, in much better condition and "Buy it now" only $10 more than your opening bid... http://www.ebay.com/itm/5-Las-Vegas-Riviera-Casino-Chip-VG/351780238881?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D37184%26meid%3D885469879a2c48adb4df8b8cb7d57a1b%26pid%3D100005%26rk%3D3%26rkt%3D6%26sd%3D162136728284

Regarding your other chips, I haven't seen others on so you will be setting the market.
