As I have understood it so far it was a medallion that was stolen from a French museum in 1831, and apparently is gone for ever. - I just want to know how much gram was it? A byzantine Solidus is normal 4,5 gram but that one was a very special one. I have seen some of gold and some of bronze (replicas or electrotype): "Drawing of a lost multiple solidi of Justinian I figuring a lost equestrian statue of Justinian in Constantinople, struck in celebration of the victory in the Vandalic War. Photograph from Charles Diehl, Justinien et la civilisation byzantine au VIe siècle, Paris, 1901." source: https://ca.wikipedia.org/wiki/Fitxer:Justinian_Multiple_Solidi.jpg From CNG: "Justinian I. AD 527-565. Æ Medallion (74mm, 87.5 g, 12h). Nimbate, helmeted, and diademed bust facing slightly right, wearing chlamys over cuirass, holding spear in right hand, shield over shoulder / Justinian, holding spear, on horseback right, preceded by Victory advancing right, holding palm; star before head of Justinian; CONOB. A replica of the medallion stolen from the Bibliothèque Nationale de France. VF." From the British Museum: "Electrotype copies of a gold medallion of Justinian I" What was the weight and size of the genuine one? The same as a normal Solidus?
Well it was listed as a multiple solidi, so I very much do not think it was a normal solidus weight. Plus, the CNG example in copper weighed 87.5 grams, and gold is much denser than copper.
I did not know that "Replica" meant making a similar one in same size. - I thought it had exaggerate the size. So it was a gold medallion with over 90 gram gold?. -Incredibly.
The Kent book Roman Coins illustrates and gives weights of some similar but earlier pieces. They tend to be referred to as a multiple like a "Medallion of nine solidi" which is about this size and should weigh 9x the standard solidus weight or about 40g? Whatever we come up with will be nothing more than a guess. I don't have a book illustrating Byzantine medallions for comparison.
I held this coin in the British Museum recently; it exists as two halves, unfortunately. The original no longer exists - stolen and probably melted down - but the electrotype (same size) is about the size of my fingers... and I have fairly large hands.
Supposedly the original was half a roman pound / 36 Solidii https://books.google.ca/books?id=4-...=onepage&q=justinian medallion stolen&f=false
