James:

The Caesar's with the antiquing are new issues, despite the 1966 date on them. These are thus far one of a kind with the antique look and scalloped edge.

Andy is correct about the Gold Strike error saying "Boulder" but the error also says "Gold Strike" and the correct version says "Gold Strike Inn" as well as "Boulder City." There is also some variation on the flying birds but if you can't figure out the words, then the birds won't help. (If I knew Greg's icons, I'd put a smiling face here)
