How much does a T-Mobile Prepaid sim card with 60 min cost?

Question

I have 2 T-Mobile 60 Min prepaid cards and want sell them because I can't return them to the store. I just want an average cost of each card for 60 minutes.

Answer 1

$15 - $20 if you had to put a price on them. $25 pretty much buys 130 minutes and $10 buys 30 minutes of air time with T Mobile.
