Hi William,
I have the original $1 Texas Treasure and the .50. There was not a chip marked TT I as the TT II was not in existance yet. The .50 was used on both ships. There was something about a Wenesday cruise and the ships would reverse the cities during the week. The cities of course were Corpus Christi and Port Aransas. Price for the two chips is $5 shipped. I will include a Texas Treasure players card. LMK
