5 Dollars Albert Einstein

The Commonwealth of the Northern Mariana Islands has no independent monetary authority and issues no circulating coinage — these pieces are licensed fantasy issues produced for the collector market, with no legal tender function in practice. The X# reference prefix in Krause confirms this non-standard status.

The Einstein subject ties to 2005's World Year of Physics, the centenary of his annus mirabilis papers, though this piece was struck a year ahead of that commemoration.
