2 Cedis Albert Einstein

Ghana has issued commemorative titanium coinage since the early 2000s, contracting production to European mints — this piece almost certainly struck by B.H. Mayer's Kunstprägeanstalt in Germany, which has handled the bulk of Ghana's collector series. Einstein himself had a documented connection to a different kind of currency crisis: stripped of his German citizenship by the Nazi regime in 1933, his bank accounts were seized before he emigrated permanently to the United States. The Institute for Advanced Study in Princeton paid him an annual salary of $16,000 — which he reportedly tried to negotiate down.
