I know these are terrible scans, but it is the best I can do. The coins just aren't in good shape. Can you see enough to make a guess as to who the emperor is? Anything you can share about the reverse would be appreciated too. Thanks. A very old, but living lady.
Antoninus Pius. That's your emperor. Someone else can help you with the type and other details. The diameter in millimeters and weight in grams would be helpful to know, as would larger photos, obviously. Here is my Antoninus Pius sestertius.
PS- here is the writeup on mine. There is a picture of the slab at the bottom of that page, to give you some idea of the scale, if you are familiar with third-party slabs. (I suspect you must be, since you have a coin shop logo as your avatar.) Mine is 31.7 mm in diameter, so the size of a US half dollar. Is yours that big around? If so, it too is probably a sestertius like mine.
Welcome to Coin Talk, Living Lady! I think that is a fine-looking Antoninus Pius AE. As others suggest, diameter and weight would be helpful to identify. Sort of guessing, but here is one of mine (a sestertius) with Aequitas on the reverse. It sorta looks like yours: Antoninus Pius Æ Sestertius (148-149 A.D.) Rome Mint AN[TONI]NVS AVG PIVS PP TR P XII, laureate head right / [CO]S [IIII] S-C, Aequitas draped standing left, holding scales and cornucopiae. RIC 855; Cohen 232/Fr. 4. (28.62 grams / 30 mm)
Antoninus Pius for sure. The reverse deity holds a cornucopiae and maybe that is an altar at her feet. Salus, maybe?
