What is a Widow's Mite Coin?

By GovMint :

The Widow's Mite coin refers to small bronze coins, known as lepton, minted during the reign of Alexander Jannaeus, King of Judea, from 103 to 76 BCE. These coins are famously associated with a biblical story in the Gospels of Luke and Mark, where a poor widow donates two small coins, representing her entire livelihood, to the temple treasury. The term "mite" was later used to describe these coins, although it originally comes from a Dutch word meaning "small cut piece."  Lepton was the smallest denomination in circulation in Judea at the time, worth half of a prutah. These coins typically featured an anchor and a star design.
