After searching for over a year, I have finally found a set of the Corningware piggy banks. Produced by Corning Glass Works in the 1980’s, these rare banks were made available to Corningware employees for purchase. I do not know what the employees paid for these banks when they were released, but these are a highly collectable item by Corningware collectors today which fetch prices of $50 or more per bank. These banks are very small about 7″ across, but a must have for a serious Corningware collector. If you should ever come across one of these in a thrift store or yard sale- GRAB IT. These are extremely hard to find.
