I managed to snag a chip tonight on eBay that I had to dip into the funds to get, but I think it's worth it. For bid, one $5 chip from the Cal-Neva Lodge, which dated to the period when Sinatra owned the casino. And I managed to get my final bid in under the wire, so I couldn't get outbid again for it.
So much for the rest of my chip purchasing funds for the rest of the month, but I don't care... I got myself something I can really appreciate. Helps that I have Sinatra on in the background...
