When I listed a McCoy Blushing Apple cookie jar a couple weeks ago, I noticed there are a lot of fakes and reproductions in the McCoy pottery category.  The Mammie cookie jar is rare; there is no way a dozen of them could be appearing on eBay simultaneously.  Plus, the Mammie was only made in three colors:  solid yellow, solid aqua, and white with black face, hands, red do-rag and sometimes more details like a red and white checkered apron.  The "cold paint" red and black - applied over the glaze - is worn or almost gone, and the originals are 11" tall versus 10 1/4" for the repros.  The Mammie with Cauliflower is very rare:  it was a limited edition item.  I go to a lot of auctions out here in West River South Dakota, where genuine McCoy, Fenton, and Depression glassware items are few and far between.  There are lots of fakes at some regional auctions, and they are getting into eBay auctions either knowingly or unknowingly to the seller.  Beware!  Buy only from sellers who accept returns in case you get stiffed.  Preferrably buy only from sellers who photograph their items from all angles, including the bottom.  Fake McCoy and other ceramics are generally signed with the stolen logo, but the feet of these items is lily white, as are the interiors, i.e., no wear.  I don't mind buying a cookie jar with some crazing and discoloration because I know it's old, and made in the U.S.A.  The best insurance against fakes and repros is education:  buy yourself good price guides in your favorite collecting areas and study them.  Soon you will be able to spot fakes at a glance.  Informed collectors are smart collectors, and honest dealers and other sellers appreciate them.  Happy hunting!
