I don't recall ever seeing one like this before. No sides are left .. Thought it was a button when I dug it.
Not worth anything, but it has my curiosity!

Probably an "Eley Bros. No. 12 London" shotshell :

Major ammunition developments that have come from ELEY include...and thin-brass totally waterproof shotshell cartridges, in 1882.
