The Half-Shekel denomination
The Shekel was a denomination weighing about 8.6 grammes and mainly used by the Phoenician - or Punic - city states and in Judea.

In the New Testament, Tyrian Shekels are hypothesized to be the infamous '30 pieces of silver' given by the Romans to Judas.

Shekels were also struck in gold, but obviously to a different weight standard. Fractional shekels were also struck.
