Watch List notes:

LESBOS. Uncertain early mint. Ca 500-450 B.C. Billon stater. 11.15 gm. 20 mm. Two calves' heads confronted, heads butting; or, looked at another way, they form a single head facing front; between them, laurel or olive tree / Small incuse square. SNG von Aul 1682. SNG Cop 285. Traité I, pl. XV, 14. Very Fine; nicely toned; well centered, clearly struck, and pleasing.Lesbos issued unusual types that can be viewed in two ways, creating a fascinating optical illusion (shades of "Magic Eye"): in this instance, the two calves' heads on the obverse can be seen as separate animals facing each other, or as the single head of a powerful bull with massive shoulders facing out.
