1974 Philippines Proof Set in nice condition

Description

Republic of the Philippines 1974 Proof Set from the Bangko Sentral. It contains coins from the F
ilipino Series. In 1967, Philippine coinage was changed to reflect the use of Filipino names for the currency units. These Filipino coins bore portraits and profiles of Philippine heroes, with legends inscribed in Tagalog, the national language.
Only 10,000 proof sets were made. Each set contains 6 coins: 1 Piso, 50 Sentimos, 25 Sentimos, 10 Sentimos, 5 Sentimos, and 1 Sentimos. Many of these sets were exposed to the tropical humidity in the Philippines and many of the coins in these sets now have spots, hazing, and corrosion.
I bought this set many years ago and brought it to the USA, where it has been kept in a humidity free environment. There are some light spots on the 1 Piso and 50 Sentimos. The 5 and 1 sentimos show some verdigris on their rims. I don't see any problems on the 25 and 10 Sentimos.
Please view the photos to see for yourself.
I doubt you will find a nicer set.
I have listed other coins, notes, and tokens from the Philippines.
