Dear Marvin,
By "unpublished," I mean it is a coin
type (or variety)
still largely unknown to
numismatics, not yet published in the current literature (such as a coin
catalog) or academic databases (such as Corpus Nummorum,
RPC Online, etc.). Even now, with the flood of new coin
types hitting the market, many more remain to be discovered. This is especially true with
Roman provincial coins, but also with very small Greek bronzes such as your piece, which has apparently slipped through numismatic
history to the present mostly unobserved, precisely because the coins were so small in size and easily overlooked.
Best regards,
