Dear Charlie and Board,
Yes, this is definitely a
Coela issue, of probably
Antoninus Pius. This city's coins contain so many different
types and varieties that it is little wonder why you didn't find an exact match for your piece. The catalogs of
RPC Online and Corpus Nummorum are
still incomplete. I have several unpublished
types in my own
collection that I haven't gotten around to publishing yet. It would be nice if numismatists start cataloging the prow types/varieties based on the
ornamentation on the prow in addition to other details.
Hope this helps.
Best regards,
Mark Fox
