Incredible, you will have to commit to telling those around you, to the little children around you, you will see their eyes shine when you calculate the age of this tiny thing of 2.29 grams of silver... Then they will be able to learn what What was Megalopolis, what was a lagobolon, who were Pan and Zeus…. Private collection object, authentic patina of use, piece of a hemidrachm from the city of Megalopolis, in silver. Diameter 14 mm, weight 2.29 grams. Rare item. On the obverse: Anepigraph (coin without legend) where the head of Zeus Lycaios (with his laurel wreath) looking to the left stands out. On the reverse: the God Pan is seated on a rock, he raises his right hand while the left holds his lagobolon (stone thrower). We also see an eagle ready to take flight and a triangle which I don't know how to read. I read on the internet that this piece comes from Arcadia, (part of the Peloponnese) Please read the details on the Arcadian league on the web. Amazing.
