But at least I found something....

I'm pretty sure those chips are a little sleepy....being ZZZZ's. I got 3 of each color other than blue. (Only 1)
O'Conner is Oregon ( good for trade on reverse)
Alibi is Marysville, Ca I picked up 5 all in similar worn shape(but they still exist)

I found this post card interesting with the postmark saying .....Last Frontier Village..1956 I have never seen the postmark before....but then again I don't really look into that sort of thing normally 😀


(Front of postcard) It shows that these casinos were most likely active on this date. 60 years ago..WOW!!
