This 8 sided medal was given out from the American Poultry Association – Standard Bred Exhibition in the 1930's – 1940's. Overall size is 1 ¼" in height and width. Otto Josten opened a small jewelry shop in Owatonna, Minnesota in 1897. Most of the Josten jewelry does not have Owatonna on them but this Josten piece does. I believe this is copper, it has the copper color. In excellent condition only needs to be cleaned.
