A-type banknotes entered circulation mostly in the eighties, with the largest denomination of this type entering circulation in 1991. 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.
