There has been at least two of these sets of Ebay. It is a beautiful set in a wooden case containing 500 chips (red, green, black, grey).

Here is a link to the most recent closed auction http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=6161259877&ssPageName=STRK:MEWA:IT

Here is one that is still running with a much better picture

I am told them made 150 of these sets with the Binion Horseshoe name and logo. Its hard to see the chips, I will post better pictures of the chips when I return home.
