This is the 1979 proof coinage of the Philippines.
Only 3,645 sets were minted, compared to 36,516 in 1975 , and 300 million new pound coins issued by the UK Royal Mint this year).
It included two silver coins bearing special commemorative designs. The P50 coin honoured the International Year of the Child, proclaimed by United Nations to draw attention to worldwide problems affecting children, including malnutrition and lack of access to education.
The P25 coin paid tribute to the United Nations Conference on Trade and Development ( a permanent intergovernmental body ), which met at the Philippine International Convention Center in Manila. The Center is part of the Cultural Center of the Philippines complex in Pasay, Metro Manila. It was inaugurated in 1976, when it hosted an International Monetary Fund meeting. This had been part of the Marcos plan to make Manila one of South East Asia’s financial centres. Around this time, there had been a frenetic phase of building that would transform Manila’s skyline, including 12 luxury hotels, such as the Peninsula Manila, which opened in 1976.

I don’t regard these sets as investments, and would never sell them, but I do find them of aesthetic and historical interest. It’s good to to note nearly 10,000 views of this thread on our Forum.
