It's difficult to see, but the reverse doesn't appear to have annulets before & after the IM, so I would tentatively attribute as Krug 562/1, based on that & the second 'N' in MISNENSIS looking Roman (and the first Lombardic). I can't tell if there are annulets around the IM on the obverse.
Both Krug & Mehner are good books for this series, the latter being newer & very nicely illustrated.
