There are people who like to collect it. I know some old 2 piece shotgun ammo boxes can go for good money. I sold one a few years ago for over $400 and have seen some go for $1,200-$1,800 if you have the right ones. There is a vintage antique ammo collectors page on Facebook with over 3,000 collectors and I always post my stuff on there to see if I have something good and they will let you know if what you have is valuable.
