Until 1833, these three buildings provided the United States with hard currency. Operations moved to the second Philadelphia mint in 1833, and the land housing the first mint was sold. In the late 19th or early 20th century, the property was sold to Frank Stewart, who approached the city, asking them to preserve or relocate the historic buildings. With no governmental help, the first mint was demolished between 1907 and 1911. Now, only a small plaque remains to memorialize the spot.
