4 Tari - Antonio Manoel de Vilhena

Antonio Manoel de Vilhena served as Grand Master from 1722 to 1736, and his tenure is better remembered for fortification than finance — he commissioned the fortified town of Vilhena (now Mdina's main gate complex) and Fort Manoel on the Marsamxett harbour. The 4 Tari occupied a mid-denomination role in the Order's bimetallic coinage system, where the Tari was subdivided from the Scudo, a monetary structure the Knights had maintained through successive Grand Masterships since the sixteenth century.

The KM#170 attribution places this within a short striking window of six years, after which die revisions or administrative changes produced distinct successor types under the same reign.
