In May 2015 Ebay seller quad_scheune_hamburg_finde_ich_gut from Hamburg, Germany was offering this Jordan plate. He is selling it as used which it most certainly is not.
This plate is obviously mint, unused and is of a design that was never used in Jordan. At best it can be described as a failed test design. Since he is a dealer based in Germany, it was probably made by a German manufacturer before ending up in a scrap pile somewhere.
Do not buy mint plates or you will end up with rubbish in your collection.
