Very rare, no examples in the recent sales record. As discussed by Lorber, these enigmatic coins were likely struck in Alexandria and shipped to Greece in support of Ptolemy's allies there and where they found widespread acceptance and usage. Antoher theory is that they were struck in Greece at a mint operated by Ptolemy and used to pay Egyptian soldiers sent to aid local allies of Ptolemy.
