ANCIENT COINS, GREEK COINS, Lesbos, Unattributed Early Mint (c.500-450 BC), Billon Stater, confronted heads of two calves, as if to give the impression of a single facing head, an olive-tree between them, rev incuse square with an uneven surface, 11.05g (BMC 46; SNG Copenhagen 285; SNG von Aulock 1682). Dark tone, very fine.
The obverse of this issue presents an interesting optical illusion, that of the two confronted calves' heads appearing as one facing head.
