I noticed that two German States - "Landgraviate of Hessen-Darmstadt" and "Electorate of Pfalz" - both have a "zoll pfennig" coin. I looked online to find the difference between these and a standard pfennig.
On a Coin Community Forum thread (https://www.coincommunity.com/forum/topic.asp?TOPIC_ID=276589), I found the following:
"As for the Zollpfennig - I tried to use my 'best' knowledge of German to google 'was war ein Zollpfennig'. Among the irrelevant results and auction listings, I found a German forum thread that had a reply to this question:
Der Zollpfennig musse z.B.bei einer Brücke, Tor ,Grenzstation oder beim Durchqueren einens bestimmten Gebietes entrichtet werden. In der Kurpfalz war der Zollpfennig I'm normalen Zahlungsverkehr 1,5 Pfennige wert.
So, among others, the Zollpfennig had to be paid at a bridge, gate, border station or when crossing a certain area. In the Kurpfalz the Zollpfennig was worth 1.5 regular pfennigs in normal circulation."
I'm curious - why did only these two states have zoll pfennigs and nobody else? Were these a failed experiment, and that's why they weren't continued for subsequent years, or was the mintage sufficient that no more were needed?
