You lucked out today TMH!!! As far as my June 2008 edition of "Coins" goes, the prices are as follows:
1950A (non-star) - Priest-Humphrey (signatures) - Fine:10.00, XF:18.00, CH CU(63):25.00, GEM CU(65):35.00
1950A (STAR) - same signatures as above - Fine:10.00, XF:20.00, CH CU(63):60.00, GEM CU(65):80.00
The above info is for the five dollar bills. Pretty good right - it get's better...
...Below is the info on your ten dollar bills.
1950A (non-star) w/ Priest-Humphrey signatures - XF:30.00, CH CU(63):70.00, GEM CU(65):90.00
I'd say that's definitely "stickin' it to the man". Even if they were in "fine" condition, you have 140 dollars worth of "old money that you paid fifty bucks for. That is SWEEEEEEEEEEEEET!!!!!!!!!!!!!
