One of the factors to be considered when minting coins is the material value of the currency which should not exceed the assessment that it represents.

In the 80’s, the Philippines circulated small aluminum like 5 & 25 centavo coins that quickly disappeared from circulation. An economics professor said that fisher folks found the coins a cheap substitute to “Fishnet Floaters”, which cost a lot more.

A few years ago, and probably until now, Philippine coins were also being smuggled to South Korea and used as a cheap (and illegal) substitute to Korean coins when purchasing products in vending machines and when using public telephones.
