The reverse of this coin shows the capital letters SPQR over an eagle with open wings and even open beak. Surely it's commemorative and it weighs 3.61 g. That's the first coin of this style that I acquire. Glad to hear any comment about this Roman.
Judaea, Caesarea Maritima. Many examples for Severus Alexander; not sure if others issued the type. Yours is on a too-small flan or has been ground down. Example from ACsearch: https://www.acsearch.info/search.html?id=2659006
SNG ANS has ten coins of Severus Alexander with this design, but the only one which fits the weight is 816. (Caracalla, Lucius Verus and Macrinus also have similar reverses)
I think I've recently seen a Marcus Aurelius and Lucius Verus with the same reverse motif from the same province. SA is MUCH more common. Here's mine... Severus Alexander, Ruled 222-235 AD AE21, Samaria, Caesarea Maritima Obverse: IM C SEVER ALEXANDER, laureate head right. Reverse: C I F AV F C CAE METROP, eagle standing right, head left, supporting wreath with SPQR in center. References: Kadman 97, SNG Ans 808 Size: 21mm, 9.98g It looks like yours, @7Calbrey, is a smaller, lighter flan? (trimmed?) There is no space for a legend remaining on yours.
Thank you for these detailed info. The coin was surely struck in Samaria. Wildwinds adds the term "Strato's Tower" to that. At hand, I feel I have Alexander Severus on obverse. There are some varieties for this issue as well.
