### User's Query:
Name the country with fastest growth in adjusted net national income in 1980 and state the currency used by this country.

### Extra Knowledge:
fastest growth refers to MAX(Value); IndicatorName = 'Adjusted net national income (annual % growth)'; Year = '1980'; currency refers to CurrencyUnit;
SELECT T2.countryname, T1.CurrencyUnit FROM Country AS T1 INNER JOIN Indicators AS T2 ON T1.CountryCode = T2.CountryCode WHERE T2.IndicatorName = 'Adjusted net national income (annual % growth)' AND T2.Year = 1980 AND T1.CurrencyUnit != '' ORDER BY T2.Value DESC LIMIT 1
