I’m sorry for the late reply. Thanks for the very informative responses. I’m still trying to get the exact die and mint of this coin. It’s hard to track down the exact design in the archives as other derivations are very common. I will reply back with a better shot once I bust it out of its holder.
I don't understand. Furryfrog2 already IDed your coin ("224 AD Obverse: IMP C M AVR SEV ALEXAND AVG, laureate, draped bust right Reverse: P M TR P III COS P P, Jupiter standing left holding thunderbolt and sceptre.") The catalog number is RIC 35. What additional information are you looking for? Here's another example of your coin, in case it is helpful: https://www.acsearch.info/search.html?id=7134593
I also have a Severus Alexander denarius RIC 173 (222-228) IMP C M AVR SEV ALEXAND AVG PROVIDENTIA AVG .. and a Sestertius RIC 618 IMP SEV ALEXANDER AVG / VICTORIA AVGVSTI I prefer not to judge any decisions/preferences. I have my own preferences in numismatics. Larry, nobody here is going to force you to become a collector, but I can advise you to study your coin, understand how @furryfrog02 (correctly) identified it (nice coin BTW) try reading about Severus Alexander and perhaps other emperors and generally about ancient history and you might like it and might develop a new hobby. It is true that there are coins in the world that could make you VERY rich. Not the case with yours, in my opinion it was a very nice present (I wish somebody could offer me this kind of presents, I am forced to buy them myself ). Being your first ancient coin, I think it would be better to stop thinking about the value.
