Wow! Thank you for the info. It’s certainly helps make the article more relevant for me.
BTW, how in the world did you find the “Histamenon noumisma?”
I obtained it at an auction ~ 10 years ago, along with this one below.
That jeweler and I did the same thing with this second one which was minted during the solo portion of the reign of Constantine VIII (1025 -1028 AD).
It does not have quite so high a relief, but it is ~ 1.5 x larger in diameter (roughly the same weight in gold though):
FReegards!
