Denier - Henry II unknown Frisia mint

Henry II inherited a deeply fragmented coinage network in Frisia, where local lords and bishops had long operated mints with minimal imperial oversight. The deniers attributed to unnamed Frisian workshops during his reign reflect that decentralization — the issuing authority is imperial in name, but the physical production was almost certainly delegated to regional ecclesiastical or comital administrators whose identities the surviving documentary record has not preserved.

The Ilisch NL1 references distinguish at least two die groupings within this type, suggesting more than one workshop was active, possibly in sequence rather than simultaneously.
