After my Google searches on the subject proved futile, I'm going to assume that the Bangko Sentral did not. What I found instead was the following nugget in a Philstar.com story headlined "Vatican representative to lead UST's Quadricentennial celebration":
Today, the Banko Sentral ng Pilipinas (BSP) also launched the commemorative P200 bills bearing the overprint of the UST’s 400th years logo. They would be distributing P2 billion worth or 10 million pieces of these bills.Whoa. So I guess Ateneo's 150th anniversary does not "have both national and international significance" or "meet the very high and rigid standards" of the "very discriminating" BSP?
Of the 10 million pieces, 400 of them were uncut in pairs.
BSP-Bank Notes and Securities Printing Department director Nestor Salanio said that the rest of these specially issued bills would be made available next month.
“It is also worth noting that this is the only about the 11th or 12th of a print approved by the BSP and president of the Philippines for the last 20 years. BSP is very discriminating in printing anything on our currency and it has to meet the very high and rigid standards of the BSP. The celebration should have both national and international significance and I am very happy to say that UST is able to meet these very high standards of BSP,” Salanio said.
(Uh, not really. But I will—probably—if La Salle gets a commemorative note for its centennial next month.)
[7 November 2011 Edit]
No commemorative bill was released for Ateneo de Manila's Sesquicentennial but one was issued for Ateneo Law School's 75th anniversary. There's something wrong there.
A special note was also issued for the De La Salle centennial.
