This one looks like your typical Rome style Maiorina of Magnentius from the first half of 350AD. What sets it aside is the weight. At 7.03g is cca. 50% heavier than the median of the type. MAGNENTIUS AE2 25mm 7.03g Maiorina (?) (aVF) AV: DN MAGNEN - TIVS PF AVG; bare-headed, draped, cuirassed bust r. A behind bust REV: GLORIA ROMANORVM; Emperor on horseback spearing barbarian with Phrygian helmet, shield and broken spear under the horse. * in right field. EXE: RE, Rome mint. REF: RIC VIII Rome 197, second series early to June 350AD. At these dimensions, this spec seems to have more in common with the AE1 Double-Maiorinae of 352-353AD than regular Maiornae/Centenionalii of the 348-350AD, although occasional such pieces that exceed 6.50/7g are known.

That is a rather large/heavy coin. My only Magnentius weighs in at 3.8g. MAGNENTIUS AE3 OBVERSE: DN MAGNENTIVS P F AVG - Bare-headed, draped and cuirassed bust right; "A" behind bust REVERSE: VICTORIAE DD NN AVG ET CAE, two Victories standing facing each other, holding wreath between them inscribed VOT V MVLT X in four lines. Epsilon over IS in lower centre. Mintmark PAR in exergue Struck at Arelate 350-3 AD 3.8g, 20mm Arles RIC VIII 177
Wow! I would not mind getting one of those. I still need to eventually nail down a nice AE and AR of Magnetius Interesting history behind these coins!
