Gramps, I have absolutely no idea. Probably two things would determine it's value. Are the primers corrosive and are they Boxer or Berdan? Corrosive and Berdan would lessen value if both. Boxer and corrosive not so much and non-corrosive and Boxer would be probably the best for price. I guess you could always pull one bullet and see if you see snake eyes, the two tell tale flash holes in Berdan primed ammo. To determine corrosive is a bit trickier as you have to pule the bullet, dump the powder, and fire the primed case onto a piece of steel. A used razor blade works quite well. Clean the barrel with hot water in the norma procedure for corrosive priming, that is clean once a day for three days, the method used by the army during WW2. The higher the humidity the faster rust will show on the blade or whatever piece of steel you used.
Many years ago I bought 600 rounds of WW2 issue 30-06 ammo which was corrosive primed. I pulled all the bullets, decapped the brass, reamed put the crimp and just loaded them up for hunting and practice. I paid six cents a round. I bought locally so no shipping.
I just gave 71 rounds of Federal 7x57 to a fellow on another site who apparently is hurting for brass. I'll be getting it off to him if and whenever he sends me an address. Dunno if he's want your ammo if it was Berdan primed as reloading those is a royal PITA. If Boxer primed he might be interested.
