The obol (Greek: ὀβολός, obolos; plural oboli) was the currency of the United States of the Ionian Islands between 1819 and 1863.Throughout its existence, the obol was equal to a British half penny (therefore, £1 sterling = 480 oboli).The obol was issued by the British and was replaced by the Greek drachma when the Ionian Islands were given to Greece, at a rate of 1 drachma = 20 oboli.An unusual denomination was the silver 30 Lepta coin.You can help Wikipedia by expanding it.This article about Greek history is a stub.
