They are generally worth a few $$ under what a fresh off the shelf box of the same would cost you.
They are shooter ammo, and 1 1/4oz 12ga loads (lead) are not exactly popular for most shooters these days.
The hulls likely have the early Remington #57 primer in them. Slightly smaller in dia than the standard #209 that was about to take over the industry.
So the paper hulls are reloadable with the older #57 size primers.
Sometimes you can force a #209 into them and swage the primer pocket to size doing so.
But the paper hulls are only good for 2 or 3 loadings before they start to perforate around the brass.
Most people with repeaters don't like the separate base wad they have and won't reload them at all, or only one time.
What can be of value is a pristine box, even an empty one.
Shoot the ammo up, have fun with it, you'll never find any cheaper now than what you likely paid for it that back when.
A couple rounds of Sporting Clays or Trap with those heavy loads would be great knock yer self out fun.
We did that some time back with a flat of reloads I bought at a show for 50cents per box. They looked good!
All AA cases with 1 1/4oz loads of some forgetable Winchester powder listed as the fuel.
An aged Remington Sportsman 48 w/a Polychoke gave everyone a chance to shoot Skeet and beat themselves up a bit.
Stuff like that seems more fun when you're younger I guess.
Keep the best boxes, wrap in clear wrap and see if they sell at a go-away price at a show.
Some sell them 'knocked-down-flat'. Easy to ship that way and easy to protect while shipping.
