Fun painting! Portrait of a Man with a Roman Coin by Hans Memling c. 1480 Oil on panel 31 cm × 23.2 cm (12 in × 9.1 in) Royal Museum of Fine Arts, Antwerp Here's a close-up of the coin: Anyone care to guess what the reverse type might be?
You should go to Belgium anyway, it is wonderful. Antwerp is a nice town. Also amongst my favourites are Ypres, Bruges and Ghent. In Ghent you can see the altarpiece.
The thing that puzzles me about this coin is the part of the obverse legend circled in yellow below: As far as I could determine, RIC lists no Nero sestertii with the apparent legend: NERO CLAVD CAESAR AVG GE PM TRP IMP P P All similar legends have GER rather than GE. I suspect the artist made a mistake by omitting the R, and attempted to correct it by combining the E with the R. If you assume that the legend is supposed to be NERO CLAVD CAESAR AVG GER PM TRP IMP P P, then RIC lists a multitude of reverses including Adlocutio, Annona, Arch, Congiarium, Decursio, et al., so it could be any one of a number of reverses.
