The A-type metallic coins entered circulation in the eighties. They are currently demonetized because they belong to the monetary unit that remained valid until December 31, 1992. This means that they are no longer legal tender and cannot be used to carry out transactions. Their current value is equivalent to one thousandth of their denomination.
