A topic on the German states predecimal system would be useful too.
Well, you could begin with Charlemagne who, in 793-94, introduced a new pound (fr. livre, de. Pfund), with 1 Pfund = 20 Schilling = 240 Pfennig.
Now let's skip a couple of centuries, currency reforms and monetary unions.

When the German Empire was established in 1871, the Mark (1 Mark = 100 Pfennig) replaced various systems, such as ...
1 Taler = 30 Groschen, 1 Groschen = 12 Pfennige (e.g. Prussia)
1 Taler = 30 Groschen, 1 Groschen = 10 Pfennige (e.g. Saxony)
1 Taler = 48 Schillinge, 1 Schilling = 12 Pfennige (e.g. Mecklenburg)
1 Taler = 2 1/2 Mark = 40 Schillinge, 1 Schilling = 12 Pfennige (e.g. Hamburg)
1 Pistole/Louisd'or = 5 Taler, 1 Taler = 72 Grote, 1 Grot = 5 Schwaren (Bremen)
1 Gulden = 60 Kreuzer (Southern countries)
1 Franc = 100 Centimes (Alsace)
And that is only the simplified version ...
