Have you gotten yourself a 100-peso bill with the UP Oblation logo on it?
I asked because it seems like the bills are now widely circulated. For one, some PMT readers posted comments in the article Limited edition Php100 UP Centennial bills that they are selling their bills (at a premium, that is).
Last month, I dined at Jollibee Philcoa and the change I got consisted of one UP Centennial P100 bill. A week later, I got another UP Centennial bill as change from Greenwich Philcoa.
Then last Saturday, I withdrew cash from a UnionBank ATM in Ortigas and, to my surprise, the ATM churned out five crisp, brand-new bills (see photo below).
