How much are my Tony Lama Boots worth?

I purchased a pair of Tony Lama boots at an auction over a month ago. They are grey and are in fair condition. The bottom of the soles looks great but the leather has scuffs and what looks like paint marks. I'm having a yard sale soon and want to resell them. I was going to price them at $10 since they are Tony Lamas but realized the Rec. No. is 8/13/59. So, I'm thinking these boots were made in 1959! Does this mean they should be worth a lot more since they are vintage?? Please give me any thoughts or advice. THANKS
