Not planning on collecting these, no idea what they would be worth in a trade for chip/chips...Picked up a key from the Aria Sky Suites which I think are the exclusive suites @ the new Aria casino...Seems to be in new condition with no scratches or anything...Email me if you would like to offer something in trade for it...open to pretty much any thing in chips since as you know, I'm just getting the collection started...Thanks in advance, Alan
