I just saw a Harold's Club Slot Card (Reno) on eBay bid up to $255.00. Tell me this isn't so...

Did I read it correctly, its claiming to be the 6th confirmed copy known. I have two in my collection, does this mean I have #7 and 8? How about a worn Harold's Check Cashing Card?

I thought Harrahs came out with the first slot card in Reno. I have a copy, blue with red letters, with keypunch holes (no magnetic stripe).

Can anyone confirm this infomation?

Can we find this info in the Slot Card book on the market today... I guess I should go buy one.
