I used to have a brand new box of Remington 410’s that were from the late 30’s. Somehow the box got stuck in the bottom of my Dad’s old heavy canvas backpack for 30 years. When I found them again I flipped out. I wrapped the box with paper and stuck it in a Crown Royal pouch for another 25 years. I finally sold it to a collector for a very tidy sum.
I’ll bet, ammo with the box (especially in good condition) brings a good price.
