It is what it appears, a Token/medal for their Bi-centennial. Lots of small towns and cities have them minted for assorted celebrations, My city had some made for the big deal in the 70's few if any I have found even knew the they were made. Since civic things and info about them seems to get lost faster than, rain water going down the gutter. People that took part die or forget about them in a trinket box, to be found by relatives years later. I have assembled a number of local Michigan to me ones and few of any people h seen them.
