Thrymsa 'York' group

The York-group thrymsas occupy a transitional moment in early English monetary history — the point at which Anglo-Saxon moneyers were actively adapting late Roman and Frankish gold coinage rather than simply copying it. Production was concentrated in Northumbria during the 640s, when gold coinage in England was already beginning its slide toward debased pale gold and eventually the silver sceatta series that replaced it entirely by the 670s.

The specific attribution to York rests largely on find-spot distributions and stylistic groupings established by Metcalf. No mint signatures exist.
