The Frank was the currency of the Helvetian Republic from 1798. The Helvetian Republic ceased issuing coins in 1803. Aargau issued coins between 1805 and 1831. In 1850, the Swiss franc was introduced, with 1½ Swiss francs = 1 Aargau Frank.
Billon coins were issued in denominations of 1, 2, 2½ and 5 Rappen, ½ and 1 Batzen, with silver coins for 5, 10 and 20 Batzen and 4 Frank. The 2½ Rappen was also denominated as 1 Kreuzer.
