The Western Black Sea coast had several important centres on trade and consequently a few coin types of pre-monetary items were introduced including 'dolphins', 'arrowheads' and 'wheel coins' all were cast in copper. Originally most were thought to be from Olbia but more recent hoard evidence indicates that they were mostly produced in Istros or Apollonia. These 'wheel coins' above were produced in Istros (from the ethnic on the reverse). A century or so later they were replaced by struck coins with different motifs.
