Need help identifying this. Appears to be brass. Its 2.5 wide 2 in tall. Has holes on the back top and bottom. Any idea on a date? Thanks for any input 

In answer to the material question, these are normally pewter types, although your looks copper-alloy, but not brass.Wow!... never expected to find colonial at the site I was at, just goes to show ...you never know! My son found a flat button there as well. Can't wait to go back! Thanks everyone for your help!
