These two dudes look pretty similar to my eye, and I'm not sure which of the two I have represented among these three coins. My guesses: 1. AE19. Gordian III, Artemis and animal reverse? 2. AE18. Severus Alexander. Salus seated reverse? 3. AE22. Gordian III, goddess holding cornucopia reverse?
The one on the top left is similar to this one from Vimanacium, I believe. The obverse on yours might even me a die-match with mine? They look pretty close: Gordian III Æ 19 As Year 1 (?) (238-239 A.D.) Viminacium, Moesia Superior IMP CAES M ANT [GORDIANVS AVG], laureate, draped & cuirassed bust right / PMS CO L VIM, Moesia stdg. facing, bull and lion either side. [AN dot I? - year off flan] in ex. AMNG 73 (uncertain attrib.). (3.07 grams / 19 mm) Not sure about the other two, however.
Thank you!! I would have never guessed Moesia on the reverse. I could only see one animal so I figured it was Artemis.
The deity on the reverse of the bottom coin is Tyche standing l., holding rudder and cornucopiae. Consider the obverse bust might also be of Elagabalus. Don't jump to the conclusion that the seated figure is Hygieia/Salus; there are many god(desse)s that appear seated.
