This item consists of an embossed brass eagle with 2-1/8” stickpin holding a 2.25” dia. embossed disk designed like a tin plate. Text at center is “McKinley And Protection” surrounded by text “Made Of Ohio Steel & California Tin/Piqua 1891.” There are several specific references to this 1891 McKinley Governor campaign item which can be found on Google by entering “McKinley Piqua 1891.” One item relates that “Col. J.G. Battelle, Head Of The First U.S. Company To Manufacture Tinplate, The Piqua Rolling Mills (formerly of Cincinnati) organized “Great Political Meeting” in Piqua in support of McKinley. The firm produced these badges for the event. However, the New York Times of 9/30/1891 says a St. Louis group submitted an example badge to a chemist who determined the “Ohio Steel” was really “Wrought Iron Of Inferior Grade” and the “California Tin” was a very thin coating of tin and lead alloy in which the lead largely predominates. The Times article criticizes McKinley for his gullibility to the interests of manufacturers and states that if the American working man’s lunch pail were to be made of such inferior material he would surely be poisoned. Item has lt. general wear with tiny oxidation dot on right edge. VF. Rare.
