Curtis Clay 19/01/2010 about another specimen of this type:
"I would say that this Serapis type is scarce on denarii (18 specimens in Reka Devnia hoard), rare on sestertii.
The British Museum has a sestertius, purchased from Feuardent in 1869, whose reverse only is illustrated in BMC, pl. 110.3; it comes from the same rev. die as yours.
Cohen 705 quotes a specimen in Paris, and values it at 10 francs, a bit low I would say, given the rarity and interest of the type.
No specimens in our photofile compiled from catalogues of c. 1970-1990, none in CoinArchives or Wildwinds.
I have been on the lookout for this sestertius for decades, and had a specimen in my first collection that I dispersed c. 1990. Arminius found one, which he shows above. So it is a sestertius that one can acquire with patience, but there are not many of them around!"
