I recently sold a .50c Sheraton chip to a collector located in Vegas, he bought it as a part of a lot. May be able to connect the two of you.

I still have a used deck of playing cards from there. The box is well worn, could use tape to patch it up. They've been used for the last 20years so that's pretty understandable I think.

They're on eBay at the moment if you want to have a look.
