The first one is buttonish, but has a hole in the back and is hollow. My next pic is of a piece of ornate copper maybe. I'm not positive what it is made of. Thanks for all your help fellas. I really appreciate it.
Your copper piece maybe brass and looks like a sideplate for a Brown Bess or Model 1768 flintlock. Pictured is a model 1768, but the one on a Brown Bess looks identical. Possibly used on other models??
Thanks a lot guys! I'm excited to go back. If y'all only knew how many times I have thought that I have dug a piece of a musket only to post them and find out they weren't. That's great news!
