Lepton
Lepton
is a small coin, often the lowest form of denomination (as the penny is
in U.S. currency). It is a Greek word meaning small or thin.
In Palestine, during the Roman era, lepta (plural form), were minted by Roman authorities for Jewish use.
The lepton, in the New Testament, is commonly referred to as a widow's mite, but the correct form should be Roman mite.
