Not that I know of, keep an eye on http://www.coinshows.com/texas.html
I just got back from the show in Grapevine and it was much better than the show at Lockheed-Martin center last weekend. Spent the whole day there and didn't buy a thing. Today I brought home a Trade Dollar, Bust Quarter and reeded Bust Half for my type set from the Grapevine show. I also picked up a couple Indian heads for my set. I had great luck at Grapevine last year, too.
Thanks for the info. I can't believe there is never a show in Austin. There should be.
