Sheckle

Sheckle or shekel is an ancient unit of weight or value. especially : a Hebrew unit equal to about 252 grains troy (about 16.3 grams)

2. : a coin weighing one shekel.

A half Sheckle is about 8 grams of silver.

The Hebrew shekel was the 50th part of a mina, and as a weight about 224 grains.

Shekel is any of several ancient units of weight or of currency in ancient Israel, from the Hebrew root ש-ק-ל (ShinKufLamed) meaning 'weigh' (שָׁקַל šaqal 'to weigh', שֶׁקֶל šeqel 'a standard weight'), common with other Semitic languages like Akkadian.

In the first century a shekel was equated with the Greek tetradrachm (equal to four drachms), which was a silver coin of the weight of nearly 14 grams.

Half a shekel therefore would be in the value of nearly 7 grams of silver, and could be equated with the Greek didrachm (equal to two drachms).
