Buttons and shell headstamp ID?

[GranvilleATPro]

Prob nothin special here but I'm soaking up any info I can find on relics, the good and the bad from this Wabash Erie canal ghost town, Indiana, circa 1830's-1870's. Both look like buttons, the flat one not sure though. Headstamp on shell is stamped LEAGUE, can't find any info on that though. Keepers? Or throw away? Thanks!

The shotgun shell base dates to the late 1800's.
Note that it's a black powder load, smokeless powder came along after 1900.
