Litra

[1] In silver content, the coin weighed 0.87 g (0.031 oz) and was equal to one-fifth of a drachma.

Some ancient Greek bronze coins were marked with value "pellets", which are tiny solid domed counting-dots somewhat like the pips on dice.

Because of the division into 12 parts, a bronze coin marked with six pellets was worth half a litra (a hemilitron).

A bronze coin worth one-sixth of a litra, called a hexans, often bore two value-pellets.

[4] In the Talmud, the litra is a unit of measurement, the equivalent of 60 shekels, weighing 354 g (12.5 oz).
