I saw that one (actually TWO) that close shortly..hope I can be part of the bidding. They are 1st issue, very nice condition. Heres a copy of the message I sent the seller of the caution chips. I hope I was tactful and came across as helpful/informative, not overbearing.

Hi-
I saw that you are selling this chip, and the $25 as being from the 20th Century casino, and wanted to let you know that you need to revise the listings.

These chips (although nice) were made and intended for home use only and were never used at the casino. They were made by Paulson, a professional company that supplies many casinos with the chips they use, but these are not genuine casino used chips... Note they do not show Las Vegas on them, just 20th century, and were made AFTER the casino closed. The actual chips feature the house mold, not the hat & cane.

Hope this saves you from any problems with winning bidders. LMK if you have any questions.
