I just received my first ever crusade coin! I have developed an interest in the period after the 4th Crusade and the different states created in the area
So I bought this coin which was marked as Principality of Achaea - Gui II de La Roche.
Firstly this sounds like a mistake, as Guy II was ruler of the Duchy of Athens
, not the Principality of Achaea. Of course these states were connected and their coins seem very similar. Actually all those coins look similar, so I find it hard to distinguish between leaders. Is there any reference material with clear pictures or drawings that can help
