Antique Philippine Paper Money

Obverse View of the Philippine 5-Peso Note Issued in 1921

This paper money featured in a 2014 post of mine has turned 100 years old officially.  Can you believe it?  It's insane.

The 5-Peso note issued by the Philippine National Bank (PNB) in 1921 during the American occupation has survived 100 years which officially makes it an "antique".  An object is considered antique if it was 100 years or older.  I wonder how much this antique money is valued now?  Do you know?

The obverse or front view of the money is still legible while the reverse or back view is almost wiped out. Oh, well! I still get to keep it.
