A fascinating list. But this is only the bare bones. There must be a story behind most of those nicknames.
For example, "~ the Unready": Ethelred II of
England." This is the modern version of the name, which was more like Aethelred Unraed. Literally, Aethelred meant something like "Noble advice," so as a name, might have meant "Well-Advised." "Unraed" meant "No advice" (think of the archaic word "rede" meaning advice or counsel) and could be read as "Ill-Advised." So it was a sound-alike nickname meaning the opposite of
his actual name, much like
Euergetes being nickamed Kakergetes. Some things don't change.
This sparseness of information is a fault with my list too. It's only a start. Ideally I should add an explanation and a link to an appropriate coin, if I collected those coins.
