Constantine I SOLI INVICTO COMITI from London...rare type

[Victor]

I just finished watching the latest CNG auction and this exceptionally rare coin just hammered for 3k...I was not even close; but congrats to the new owner.

CNG description--

About this issue, C&T write: "There are only six known examples of this coin type, all struck from the same reverse die, and the two obverse dies illustrated."

Commiserations Victor

is the attribution to London based on style, or an obverse die link with an London reverse?

[Victor]

Yes, it is based on style (the Sol is very distinctive from other cities); though Gautier said that although he had seen no obverse die matches, he recognized the work of engraver from other issues. Here is an older post with examples from  London, Ticinum and Aquileia and Trier. Gautier suggested that these coins were probably struck at all the mints under control of Constantine at the time; so be on the lookout for examples from Lugdunum and Rome
