My dad has this box of ammo. The primers are stamped US. Got some info about the company off the internet. Any idea how much they are worth?

Ball park figure $20.00 to $25.00 bucks,The box is in average condition,and the shells are below average ....The United States Cartridge Co,was in Lowell Mass,it is a collector box ,if in new, sealed condition,you'd get around $100.00 for it !

My 2 cents BB34

Thanks
