McCoy pottery was made in Roseville, Ohio. Nelson McCoy and J.W. McCoy established the Nelson McCoy Sanitary and Stoneware Company in Roseville, Ohio, in 1910. The firm made art pottery after 1926. In 1933 it became the Nelson McCoy Pottery Company. Pieces marked McCoy were made by the Nelson McCoy Pottery Company. Cookie jars were made from about 1940 until December 1990, when the McCoy factory closed. Designer Accents marketed McCoy pottery under the name Nelson McCoy Ceramics until the company closed in 1990. Since 1991 pottery with the McCoy mark has been made by firms unrelated to the original company. Because there was a company named Brush-McCoy, there is great confusion between Brush and Nelson McCoy pieces. See Brush category for more information.
