The back is original. The front is one of the Seals of Solomon. Unchanged in design. If it was changed it wouldn't be a Seal of Solomon.

Obviously not , looking at previous coin designs, and publicly "viewable" artwork 
Out of curiosity would you consider a painting of the Eiffel tower to be original? Or would you say a statue of the Mona Lisa is original?
