Clarification on Date: Archbishopric of Cologne Weisspfennig [gelöst]

This coin was supposedly struck in 1376 according to the CNG auction listing, but during an archbishop's reign which started in 1378.

Is this correct? (CNG is normally pretty reliable, but I can find one other mistake in this listing).

If that is correct, or if at least one subtype was struck in 1376, it would be helpful to put that in the date table in our Numista listing so the coin is findable based on that date.

confirms what you said.

but here a 1376 coin seems to become probable?

again 1376 is fully possible

Sorry, guys. I just added the links in the original post (a careful eye will notice some similarities between the coin that sold recently at CNG, and the one in our listing ).
