Whats is 700 rds of FN .45 acp ammo worth look inside for specs and details

[Jimmy Deuce]

I have a friend who has about 700 rds of .45 acp ammo.
Produced in 1955
Made by FN
Berdan primed

All rounds do not work my guess is do to the primers going bad.

Any idea if what its worth if anything?????

Thanks
