The Bangko Sentral website was updated weeks ago and, surprisingly, they are now selling Bagong Lipunan, Pilipino Series, and English Series banknotes. What was more surprising? They were selling the notes at their former face value!
Thus, a 200 piso note from the English Series is also selling at 200 pesos. That is quite a bargain since, I would assume, they only offer uncirculated notes. Buying similar items at ebay or collector's shops would cost you much more. The website is also selling other commemorative coins and banknotes at relatively bargain prices. Of course! You're buying directly from the maker.
To order, you need to place an online inquiry and include your full name, contact number, and email address. Just hope they soon respond to your query. Last time I inquired about a commemorative coin they responded after more than a month.
