Great finds! Those TI chips aren't worth too much, but they are still one of my favorite chips! I wish my local coin shop had anything casino related. The best I have found there are some airtites and a few tubes. I even went to a coin show (which boasted they had everything for numismatics) a couple months ago in Raleigh. I looked around for an hour and didn't see a single casino chip or token. Every once and a while I see a casino chip at the flea market, but its usually a current chip that looks like someone had dug it out their back yard.
