4 Tari - Jean de Vallette

Jean de Vallette served as Grand Master from 1557 until his death in 1568, and the entire span of his magistracy was dominated by the Ottoman threat that culminated in the Great Siege of 1565. The island's finances were perpetually strained by fortification costs and the maintenance of the fleet, making silver coinage of this period functionally important — not ceremonial.

The 4 Tari was the workhorse denomination of Hospitaller silver, used extensively in commercial transactions across the central Mediterranean. Restelli #21 is among the better-documented types of the magistracy.
