The top image below was originally posted by me some time ago. It shows a modern gold imitation of the
hyperpyron S.2073 (with the
reverse upright when it should be inverted), together with what appears to be a
cast copper copy of the gold coin.
The 3rd
coin shows another example of a
cast copy, currently on offer by a prominent
auction house.
The bottom
coin shows what seems to be an earlier offering of the current coin.
