Roman battlefield found deep inside Germany

[Gluteus Maximus]

coin evidence might not be very useful for dating here as legionaries would have tended to hoard the older,purer and more valuable coins.

They would - but then, the coin evidence remains quite interesting, because that coin of Commodus looks very worn! Just a point about the lack of Germanic weapons, and the possibility this might have been a battle largely - or mainly - involving Germans. Maybe at this point in history Germans did not need to make weapons? I mean, the Rhine and Danube frontiers hemmed them in on two sides. Why bother with making the stuff yourself when you can trade items and buy weapons ready made, and to good Roman standards? Were the Fabricae that well organised by the state that they would be picky about who they supplied stuff too?
