Yes, I have one of those, too: double die match. I only have this
obverse die three times, the third one just recognizable because of corrosion compounded by bad cleaning (but certain). The three reverses are
Asklepios,
Serapis, and Haimos. When I got the
Serapis two years ago, I wrote, "Neither die located in
Pick,
AMNG, or
Varbanov, so that the acquisition [of a damaged coin] is justified." That is why I called it a
scarce obverse; one can collect a half dozen or so of most of the
obverse dies. The
Macrinus Haimos with that
obverse die (the same
obverse as for
his Asklepios and
Hygieia, as well as for some ordinary
types, such as a
Hermes) is
scarce but not
rare. But I posted the
Diadumenian Haimos because I've never seen another one--and neither
had Pick.
You have a beautiful
Diadumenian collection. For five years I have been studying the die links and groupings (sequencing the
obverse dies, if possible, by the
reverse dies that they share). As soon as I have even a tentative result, I'll be happy to share it with you prior to publication. It is astonishing how many dies they used in 14 months!
I certainly shall study your
collection, but of course not abuse the privilege!
