McCoy.....Nelson McCoy.....never made string holders. I can't tell you how many times I see these listed on Ebay as "old"..."Usual wear"..."normal wear"...most of this is followed by "the usual glaze pops and issues. Please do not be fooled into buying one of these items. They never made a cat string holder and never a mammy string holder. I do not have every book in the world, however, I do know what I have just posted is true, this comes from the McCoy Society, and a book on "Fakes & Reproductions". All the bes in your hunting and collecting!!!!!!!
