The gulden was the currency of the Swiss canton of Luzern until 1798. It was subdivided into 40 schilling, each of 3 rappen or 6 angster. Coins were also issued denominated in kreuzer and batzen. The French silver écu was equivalent to 3 gulden.
The French écu was also equivalent to 4 Franken of the Helvetic Republic, and afterwards to 4 Luzern franken.
