Vierer - Hildebrand I

Hildebrand I von Riedmatten served as Bishop of Sion from 1565 until his death in 1604, presiding over a diocese perpetually caught between the ambitions of Savoy, the Swiss Confederacy, and the fractious Zenkräfte — the seven districts of the Valais whose secular power increasingly rivaled episcopal authority throughout his tenure. The billon vierer belongs to the small-denomination workhorse coinage of the period, kept in circulation for petty transactions in a mountain economy where silver was hoarded and copper mistrusted.

The HMZ 1#2-1049 reference places this type firmly within the documented episcopal coinage of the see, though Riedmatten's long episcopate of nearly four decades means die varieties within the series are not uncommon.
