Five shillings is a crown, or a quarter of a Pound Sterling, or 25 new pence. Two farthings is change to insult a beggar with. (A farthing is a quarter penny.)
When the German Reichsmark was introduced in the 1870s, it was tied to the Gold Standard. One Mark equalled one British Shilling. However, while the Shilling was further subdivided into 12 pence or 48 farthings, the Mark was subdivided into 100 Pfennige. Which was new to Germans who were long used to 1 of the larger unit being 60 of the smaller one.
