EUBOIA. Eretria. Circa 500-465 BC. Obol (Silver, 8 mm, 0.59 g, 9 h), with a thick flan and a deep reverse incuse. Bull's head facing; above head between horns, traces of an Ε with points upwards. Rev. Octopus with body above and eight arms; all within an incuse square. BCD Euboia 326 var. (but an E cited on the reverse in error). Bold and with a splendid reverse. Minor deposits, otherwise, very fine / extremely fine.
From the "Collection sans Pareille" of Ancient Greek Fractions and from the collection of L. Mildenberg.
The name euboia means rich in cattle, so it is quite understandable that Eritrea should have chosen a bull's head for its obverse; as for the octopus on the reverse, even today the octopi caught off the coast of Euboia are prized by gourmets!
