What are the historical currencies?

Together with official currencies or crypto-currencies, Currency Converter+ can also convert to historical currencies (official currencies in some countries but have been replaced by other new currencies).

If you want to enable the conversion to these currencies, you can do it in the the Currencies section of the app preferences. If you search 'historical' you will see all the available historical currencies:

Just click the ones you want to enable and click 'Save' on the top bar.
