This might be a GW button.

I found this button a while back since a camera now i can post pic of buttons i found that need ids. this button is about the size of a half dollar the center is hard to see because a dent is pushing up from the back. The button has the same style as the GW button any ideas out there . I need a button expert to tell me. thankyou
