So @Justin Lee made a thread showing off some of the coins he had cleaned up from a recent batch of uncleaned coins and asked to see some of mine. These have been soaking in DW for probably a month now and have been scrubbed ~weekly. I decided to pull them out, and after one final scrub, try to ID them. I didn't want to leave them any longer/scrub them any more for fear of ruining them further. I still have probably 20 or 25 sitting in DW that were crustier than these. Thanks for looking Constantine AE follis. 335-336 AD. CONSTANTI-NVS MAX AVG, rosette-diademed, draped and cuirassed bust right GLOR-IA EXERC-ITVS, two soldiers, each holding spear and shield, with one standard between them, o on banner, mintmark ASIS star. Constantius II AE3, AD 347-38. DN CONSTANTIVS PF AVG, rosette-diademed head right VOT XX MVLT XXX within wreath. Mintmark SMAN (I believe it is an Epsilon but I'm not sure) Gratian A.D 367-383. AE DN GRATIANVS PF AVG, draped and pearl-diademed bust right SECVRITAS REPVBLICAE, Victory walking left, holding wreath and palm branch. D in left field. Mintmark star ASISC. Julian II AE3 355-363 AD. DN IVLIANVS NOB C, bare-headed, draped and cuirassed bust right FEL TEMP-REPARATIO, soldier standing left, spearing fallen horseman who is wearing Phrygian helmet, reaching backwards, Mintmark SIS (There's more but I can't tell what it is) Urbs Roma Commemorative AE3. 332-333 AD. VRBS ROMA, helmeted, mantled bust of Roma left Wolf and twins left, star-wreath-star above. Mintmark UNK Gallienus AE Antoninianus. Milan mint. Sole reign. GALLIENVS AVG, radiate head right / SECVR TEMPO, Securitas standing left, legs crossed, holding sceptre and leaning on column. Mintmark MS Gallienus AE Antoninianus. GALLIENVS AVG, radiate head right SECVR TEMPO, Securitas standing left, legs crossed, holding sceptre and leaning on column. I have a couple others I will post in a follow-up that I haven't been able to ID but have some interesting details. Thanks again for looking
Here are some that I haven't been able to ID but I think they have some nice elements: Possible Gallienus Unsure what this one is. Looks like it has a hand or something on the reverse Another possible Gallenius. Maybe SPES on the reverse? Honestly I have no idea.
Gallienus for sure. Not only does the obverse inscription say GALLIENVS AVG, but I'd recognize that neck beard anywhere. Compare: When you see an emperor on a mid-late third century radiate who has a pointy chin, think of Claudius Gothicus. Moreover, I think I can make out the AVR of IMP CM AVR CLAVDIVS AVG in the 8:00 to 9:00 position. Compare: Looks like Gallienus, too, by the neck beard and shape of the head. I'm about 95% sure, but not 100%. I have no idea of the reverse types of any of these.
The second coin looks more like a Quintillius (270 CE) to me, the style of the profile, and the long text makes me think Claudius II may be a misattribution. 1st, and 3rd are Gallienus.
Here's an example from wildwinds of a Quintilius antoninianus that matches up with the style of your second coin. Claudius II and Quintilius were brothers, and had similiar profiles, the best indicator for Quintilius is the long obverse legend.
