Design errors

The banknote became the subject of controversy in 2005 after banknotes printed by Oberthur Technologies of France in time for the Christmas season were printed with the President's name misspelled, the first in Philippine history. The banknotes, of which a small amount are still in circulation and are still legal tender, spelled the President's name as "Gloria Macapagal-Arrovo" versus the correct Gloria Macapagal-Arroyo. The incident was subsequently the subject of public humor as soon as the issue made national headlines. The BSP probed the mistake and corrected the error afterwards.
