Thanks for translating that,
Curtis.
I discussed the coin with Francois and he agrees it is an
overstrike, and this does appear to be the first illustrated to the best of
his knowledge. The phenomenon was recorded about a half century earlier, however. That
comes from a letter written by
Picard Duvau concerning a
Postumus overstrike, dated 1731--but not illustrated. The next closest illustration is a
Thasos overstrike in Neumman's
work (
Populorum et Regum Numi veteres inediti), from the 1780s (so slightly later than Ignarra).
I'd like to know who Baroni is so I have more research to do there, but otherwise I think Ignarra was simply unaware of the phenomenon, not being a
numismatist and instead a general antiquarian.
I'll send a draft of my write-up soon,
Curtis.
