Could some of you knowledgeable members shed some light on the ID of this coin? Sold as part of a lot of 6 AS's. Is it Fortuna seated on the reverse? Also the dimensions seem odd, it is 26mm and only 4.74gr. Insights anyone?
It could be Annona: RIC III Antoninus Pius 891 See this sestertius: http://numismatics.org/collection/1995.11.146 Yours is not a sestertius
I think I might've just got one like this last month. As as, with Annona. AP's coins of this era are interesting because he uses the old "Hadrian" titles from the beginning of his reign. See note below. Here is the OCRE listing - with 22 examples - it seems this was a big issue! http://numismatics.org/ocre/id/ric.3.ant.880 Yours is quite light, but some of these seem to lose weight as they are chemically leached under ground. It looks fairly "official" to me, but I'm no expert. Here's mine; it is rough, but it does deserve better photos - it is not quite this bad: Antoninus Pius Æ As (151-152 A.D.) Rome Mint IMP CAES T AEL HADR ANTONINVS AVG PIVS P P, laureate head right / TR POT XIIII COS IIII, S-C | ANNONA AVG in exergue, Annona seated l. holding corn-ears over modius with corn-ears and cornucopiae. (10.02 grams / 25 x 23 mm) eBay June 2023 Attribution: RIC III 880; Cohen RSC 49; BMCRE 1875-1877. "The imperial title 'IMP CAES T AEL HADR ANTONINVS AVG PIVS', is only found in the period AD 150-152, the 15th anniversary of the reign or immediately prior to it. It refers to the earliest imperial title of A. Pius 'IMP T AEL CAES HADR ANTONINVS AVG PIVS' used on coins issued in AD 138-139." Charles S on FORVM
