Constantine I SOLI from Lugdunum with COS IIII legend

[Victor]

This coin is not in RIC for the bust type, it should come after RIC 24. It is in Bastien as #554. The weight was listed as 1.3g which must be an error; I will verify the weight when I get it.

The low weight reporter may not be an error. This coin passed some times ago one at and a very low weight was also reported.

Thanks, it must just be a very underweight coin.

Extremely underweight! Not even a half of expected weight. I also thought that CNG made an obvious mistake.

But the flan is quite big and with the whole obverse legend visible.
