From 1892-1918 - 1 Krone = 100 Heller (or Filler). Before 1892 - 1 Gulden = 100 Kreuzer (or in Hungarian, 1 Forint = 100 Krayczar). Pre-1857 - 1 Gulden = 60 Kreuzer (of 4 Heller each, so 1 Gulden = 240 Heller). The Gulden was a rather heavy unit, being equivalent to about 2 Marks. In 1892 it was halved.
Although the euro can be used in Liechtenstein, (but only in large shops and a few other places), the official national currency is the Swiss Franc (CHF). Other than that major credit cards - especially Visa - are widely accepted almost everywhere.
