President James Buchanan was not married.
As is the case with all unmarried presidents, his First Spouse coin is modeled after a coin in use during his term.
The front of James Buchanan's First Spouse coin is a reproduction of the Liberty Head quarter eagle designed by Christian Gobrecht.
This $2.50 coin was issued from 1840 through 1907.
The design on the coin's back is by Artistic Infusion Program Associate Designer David Westwood.
It shows President Buchanan as a boy keeping the books in his family's small country store.
