What is the value of a box of seven 50-45 peabody ammo. are they considered rare? no camera

I'd think so, but you are talking about something in the advanced cartridge collector category. Log in to the International Ammunition Association (IAA) forum. All the serious cartridge collectors from all over the world frequent it. Find a camera (you must know someone with at least a cel phone) and post some pix there if you really want an answer.
