FORVM is offering for sale a cut dekadrachm. The sales blurb suggests that it was cut in ancient times to make change.
A few months ago FORVM offered a dazzling collection of cut coins on eBay, including this and an archaic octodrachm of Abdera. There were so many cut specimens that some lots included more than one piece!
The eBay buyer is apparently finished with the dekadrachm and is selling on consignment. (I can't recall how much this piece sold for on eBay. I remember a price in the $400s but perhaps am thinking of the octodrachm).
The surprising thing about the dekadrachm is that it is a Hellenistic-era coin. Usually cut coins are very early. Before coinage rough bits of 'hacksilber' were used and some early coins were cut up when they reached pre-coinage regions to join the hacksilber. No word on where all the cut pieces came from, or if they were found together -- did someone collect these over decades, or did they all surface in a single hoard?
It is surprising that this cut piece is so pleasingly centered on Zeus. In The Medici Conspiracy pleasing breaks on Greek vases are a sign of foul play. That shouldn't be an issue here, as no one is claiming that this dekadrachm broke while it was in the ground. It was purposely cut in antiquity, probably by someone who respected Zeus.
