Brush-McCoy Cookie Jars — there is no such thing! Although Brush and McCoy were one company for a few years, the companies went their own way in 1925. During the few years the two companies were “together” no cookie jars were made.
McCoy Pottery made cookie jars and Brush Pottery made cookie jars, but that was only after the two companies went their own ways.
There is NO such thing as an authentic Brush-McCoy Cookie Jar.
Bottom Line: If a jar is marked Brush-McCoy beware, it’s not an authentic jar.
