I tried looking for this. Need a ID

I found this at a late 1800s to 1930.
It looks like the back is broken. Maybe brass?

Just a guess, but I think that might be a snap off a line of clothing.

Looks to be a threaded cap for an old tube of K Y salve.

KT notices that the threading is on the outside of this item, most unusual for a suggested cap. Perhaps it was designed to plug a threaded hole in something. Something made by K & Y company of New York?
