500 Piso Central Bank

Issued to mark the 50th anniversary of the Bangko Sentral ng Pilipinas, though the central bank's actual history is more complicated than a clean 1949 founding date suggests — the original Central Bank of the Philippines was established under Republic Act 265 signed by Elpidio Quirino in June 1948, with operations beginning in January 1949. The institution was reconstituted entirely under a new charter in 1993, making the 1999 commemoration something of a selective anniversary count.
