Philippine Banknotes: 2011 200 Peso UST 400th Year Overprint
The University of Santo Tomas or UST, is the oldest university in the Philippines. In 2011, they celebrated their 400th year anniversary. The school was founded in 1611 and is one of the largest universities in Manila. To commemorate their 400th year, the Banko Sentral ng Pilipinas released an overprint, 200 peso banknote.
It’s a bit dirty. I don’t see much of this in circulation and I am not sure how many BSP released for public use. However, this is the cleanest one I found so far.
