The Remington caps to a shooter are probably worth $10 now as most everywhere is out of stock.
The Eley might interest a collector or English percussion rifle collector to fill out a cased set. I really don't know what a price might be though.
The primers look what I am using for reloading right now.
Wooden tray w/a card/paper wrapper. They work just fine.
What ever you can get for 100/primers I guess.
I don't think collectors would be too interested in the packages,,I can't recall ever meeting too many primer collectors either.
If you reload,,use 'em.
