Well, some old dirt was moved around on the sidewalk project in my neighborhood today. As a welcome home from Maine, I found this heavily gilded Ohio medallion. I noticed the interlocking three circles at the base of the wreath and I had a clue what it was from. I believe it is part of an I.O.O.F. badge. I found a similar one for Wisconsin online (pictured below) that includes the top bar and the ribbon. My broad guess based on the design and quality would be that it dates from 1870-1910. The 1923 Mercury dime and the Canadian dime came from another park I stopped at briefly to receheck a spot I had hunted well two years ago.
