What was done in commemoration of the 25th President of the United States, William McKinley?

The McKinley Birthplace Memorial gold dollar was a commemorative coin struck by the United States Bureau of the Mint in 1916 and 1917, depicting the 25th President of the United States, William McKinley. The coin's obverse was designed by Chief Engraver Charles E. Barber of the Mint, and the reverse by his assistant, George T. Morgan. As McKinley had appeared on a version of the 1903-dated Louisiana Purchase Exposition dollar, the 1916 release made him the first person to appear on two issues of U.S. coins.

The coins were to be sold at a premium to finance the National McKinley Birthplace Memorial at Niles, Ohio, and were vended by the group constructing it. The issue was originally proposed as a silver dollar; this was changed when it was realized it would not be appropriate to honor a president who had supported the gold standard with such a piece.
