Id help

[New hunter]

Can anyone help ID the top row items? 1st is a button, can't make out writing on back. 2nd is a flat copper, is a design but can't ID it, believe the 3rd is a carved bullet, and 4th I have no idea! Much thanks!

Really need some better photos of the button front and back and the copper piece. All I can ID now is the spencer bullet and part of the hull.
