In 1866, a statute was passed by Congress prohibiting the depiction of living persons on American currency. Nevertheless, this regulation was unexpectedly disregarded in 1926 with the inclusion of Calvin Coolidge on a special coin commemorating the 150th anniversary of American independence. To honor this event, the Philadelphia Mint released a half dollar showcasing Calvin Coolidge and George Washington on the front side. What adds to the significance of this event is that Coolidge, who was not only alive but also holding the presidential office at that time, became the sole incumbent president to be featured on U.S. currency.
