The ancient coin pictures above are present on Romanian coins through the kind permission of Mr. GLV. The coin is a variant of the one described in AMNG I at position 476a (AMNG = Die antiken Münzen Nord-Griechenlands, B. Pick, 1898).

The coin was probably struck in the 2nd-1st century BC. The countermarking operation was made for prolongating the period of the coin's circulation. It is a strong possibility that these coins were countermarked in the 1st century BC, in the years before the Pontic expedition of king Burebista.
