In April 1910, the Nelson McCoy Sanitary Stoneware Company was formed by Nelson McCoy and his father J.W. McCoy, in Roseville, Ohio. They began manufacturing and selling functional and decorative stoneware. Today, McCoy pottery is highly collectible and very sought after. I have a small collection of some of their planters from the 1960s. Many antique stores and consignment shops have McCoy pottery, but be aware, because there are many fakes out there.. Hence the term, "the real McCoy".
