This is an old Philippine 500 Peso Bill.
I guess even if you go to a bank, you can not find anymore this bill. The first 500 Peso bill was planned to be released in 1985 during the era of former Philippine President Ferdinand Marcos, but it was not officially used because of the snap election.
In February 1986, Due to the People Power movement, President Ferdinand Marcos was oust from the Palace and Miss Corazon Aquino became the president of the republic. During Corazon Aquino administration, a new 500 Peso Bill (with "Ninoy" image (Benigno Simeon "Ninoy" Aquino, Jr.) was released and officially used until now.
