Here is the listed description: Description ROMANUS IV, Diogenes. 1068-1071 AD. . Constantinople mint. Michael VII standing, flanked by Constantius and Andronicus, all on footstools / Christ crowning Romanus and Eudocia. DOC III 1; BN 1; SB 1859. Taking the normal orientation of concavity, the obverse of the histamena of Romanus is the side with the three sons of Eudocia, while Christ blessing their marriage takes the reverse. The supporters of Eudocia wished to emphasize the seniority of the sons of Constantine in the succession.Copyright © CNG 2002 Condition: Very Fine Weight: 1.40 gr Diameter: 20 mm I'm quite new to the hobby, but looking at the description, the weight alone seems to say that this is a fake, no?
Weight alone shouldn't be the only criteria used to establish authenticity, although this coin doesn't look good. I wonder if the weight you saw wasn't a misprint, maybe it was meant to be 4,40 ? This coin looks more like low grade electrum or brass.
