This large copper (32mm) rung up pretty high on the minelab Equinox, 27-28, and has some heft to it, close to 10 grams. It looks to be made of pure copper and was found in the same area as the 1640 coin. In the left image you can make out a bust looking to the left wearing what looks like a laurel wreath and a collared jacket. The other side has no discernible details. Anyone have a guess to what this is?

This is the site where it was found.
