Have a(nother) look at this thread, #29 and #30 :-

# 29 in that thread states that the " New Design Series ", dating from 1985, are the " old " banknotes, to be fully demonetized on January 1 2017. The public may continue to use them up to December 31 this year ( 2015 ). For 2016 they may be exchanged at banks for the " New Generation Currency " series.


While these notes will have no purchasing value after this year, good ( uncirculated ) examples are already worth more than face value to collectors, especially the P 500 " Ninoy Aquino " note. "
