bigdog58 asks, "I have some origingal 1958 plates from my truck. they are from Texas. Any idea what they are worth?"
Good condition, $50 to $75. Mint condition, $100 to $150. Go over to Ebay, main page, enter "texas truck license" and search. You will be surprised. A bigger surprise is run "texas farm truck license".
I will give you my wife for a pair of 1949 Oklahoma farm truck plates. She is Choctaw, a tab bit ornery, but a lot of fun when she is not cussing at you in her native tongue.
