The mintmark to the left of the eagle on this rare bronze hemiobol of Ptolemy III is a harpē; a type of ancient Greek sword which had a sickle protrusion along one edge near the tip of the blade. Lorber explains that these coins were assigned to Ioppe by Svoronos because the harpē was the weapon of Perseus, who according to myth rescued Andromeda in the harbour of Ioppe. A fun, if slightly irrelevant fact; Ioppe is an ancient port city in Israel that is also known as ‘Jaffa’ and later became famous for it’s delicious oranges. It’s also the name of my cat.
