Currently, we have this 500 peso bill with the face of former Senator Benigno "Ninoy" Aquino Jr.
After former President Corazon "Cory" Aquino died last August 2009, a lot of people suggested to replace our current 500 peso bill into this.
Just a while ago when I am browsing my Twitter account and checking some tweets, someone posted the copy of this bill. I checked it and it was different from the previous one. As you can see, former Senator Ninoy Aquino is still here with his wife, former Philippine President Cory Aquino, with their son, President Benigno "Noynoy" Aquino III, and their daughter, Kris Aquino at the right top. Also, you can see Former Philippine President Gloria Macapagal-Arroyo on the left side with the sign that she is praying.
I don't have any answers why they customized this 500 peso bill but I guess it is just for fun and no malign intention.
