Ever see a button like this?

Found this button on an old 1730's property. Found some great stuff on this permission. Connecticut copper, New Jersey copper, Ton's of early buttons and a bunch of KG3's. Oddly no older silvers, Just a 1919 merc. I've contacted every old group including the Odd Fellows and masons, from here to the UK. All have never seen it in their organizations. An old fellow member from another site found 2 very similar buttons in a gold town in California. That's the closest I've come to some help. Maybe my next step is the Smithsonian. Hope you guy's and gal's can help.
