Grosso of 6 denari - In name of Frederick II

Cremona's civic coinage emerged directly from the city's political alignment with the Hohenstaufen emperors — Frederick II's name appears on these grossi not because he held administrative control over the mint, but because invoking imperial authority legitimized the commune's right to strike silver. This was a deliberate political posture, not a straightforward attribution of issue. The city remained technically Ghibelline in its monetary symbolism long after Frederick II's death in 1250, which accounts for the extraordinary date range assigned to this type.

MIR 288 encompasses considerable die variation across that span.
