50-piso New Design Series Banknote
Depicted on the front side of the fifty-Piso is Sergio Osmeña, the second president of the Commonwealth of the Philippines. He served as president from 1944, after Quezon's death, to 1946, when the United States granted the Philippines' independence. The National Museum is featured on the reverse side of the banknote. This building used to be the Legislative Building, where the House of Representatives that Osmena presided over as Speaker from 1907-1922 was located. In 2001, the name of the Old Legislative Building on the reverse side was changed to "National Museum" (Gusali ng Pambansang Museo), to reflect the turnover made by Congress to the National Museum.
