Welcome to TNet, Klclark3! Looks like you have a piece of Spanish Silver coin that is at least a couple of hundred years old. There are experts on this forum that can tell you exactly what you have. That's a very nice old button too. Is it made out of one piece or 2. Is there a shank (loop) or any writing on the back. That will help us tell more about it!
Nice finds!! The cut coins are definitely Spanish silver from the 1700's. Someone on here will be able to give you some more accurate dates, I'm sure. The last coin is a King George copper, also from the 1700's. I'm not too familiar with these but I know other members are. Check out Bill D. (VA)'s posts from the last couple months, you will see that he has found similar cut coins.
The bigger Civilian flower button you have would date too the early 19th century (1820s-1830) the smaller flower button could date anywhere from the late 18th too early 19th C. You did not post if there was a back-mark on the button or not!
