The gulden was the currency of Neuchâtel until 1850. It was subdivided into 21 batz, each of 4 creuzer. It was replaced by the Swiss franc.
Coins
In the late 18th century, billon ½ and 1 creuzer and ½ and 1 batz were issued, together with silver ⅓, ½, ⅔ and 1 gulden. The ⅓ and ⅔ gulden were denominated as 28 and 56 creuzer, whilst the ½ and 1 gulden were denominated as 10½ and 21 batz. After 1799, only the billon coins were issued, with the last coins struck in 1818.
