The balboa replaced the Colombian peso in 1904 after Panama's independence. Balboa banknotes were printed in 1941 by President Arnulfo Arias. They were recalled several days later, giving them the name "The Seven Day Dollars". The notes were burned by the new government, but occasionally balboa notes can be found in collections. These were the only banknotes ever issued by Panama and US notes have circulated both before and since.
