Copper Ring, Salt Seal, Copper statue, minie ball

[TheHbeast]

Quite a good evening. A Bavarian field permission. A nice copper statue, what looks like a minie ball, a handmade copper ring with “K” scratched in it, and a “BAYER SALZ 1” Salt seal. Only thing I could find about it was another detected find in 2011.
Strange mystery item as well.
Would love some guesses on origin and feedback!
