Right now the biggest and heaviest sestertius I got is this one Agrippina Snr Minted by Claudius 50-54 A.D. RIC 102 37 mm and 28.30 grams She says she not overweight
Not so heavy, but a companion to zumbly's Marcus Aurelius. Does anybody know why his coins say M Antoninvs instead of M Aurelius? Sestertius, Rome, 172 - 173 AD 30 x 31 mm, 26.09 g Ref.: RIC III 1074 Obv.: M ANTONINVS AVG TR P XXVII laureate, draped, cuirassed bust r. Rev.: IMP VI COS III Mercury standing l. on pedestal, holding caduceus and purse, within a tetra style temple with herms for columns. On tympanum, a tortoise, cock, ram, caduceus, winged helmet and purse in field, S - C in ex. RELIG AVG
Really nice coin! Named Marcus Aurelius Antoninus ... taking the name of his adoptive father Antonius Pius..
The biggest (non-medallic) Sestertii that I could find on AC Search are: Claudius, Nero - 40 mm Faustina I - 36,26 g
