I've learned a lot from observing here, but I can't for the life of me identify these coins. Thanks in advance
Welcome to the ancients forum! Here are my best guesses: Top right: Lydia, Sardes – similar to this one: Lydia, Sardes, AE14, ca. 133-14 BC. Obv: laureate head of Apollo r. Rev: ΣAΡΔI-ANΩN; club; above, monogram; all within oak wreath. BMC 10–21; SNG von Aulock 3125–3126; SNG Copenhagen 470–482. Top middle: Kingdom of Elymais – there are many types for differend rulers. I don't have your type with the degraded bust on the reverse, but this coin from my collection might give you a chance to compare: Kingdom of Elymais, Orodes II, early to mid 2nd c. AD, AE Drachm. Obv: Bearded bust of Orodes facing, wearing tiara, no large hair tufts at sides; to right, pellet in crescent and anchor with two crossbars. Rev: dashes. Ref: van't Haaff 13.3.2–1B. 15 mm, 4g. Bottom left: Late Roman bronze coin. The mint mark on yours is unfortunately mostly off flan, so we can't say where it was struck. The type was produced for Theodosius II, Arcadius, and Honorius. Yours appears to be Honorius, mine is Theodosius II: Theodosius II, Roman Empire, AE3/4, 401–403 AD, Antioch mint. Obv: D N THEODOSIVS P F AVG; ust of Theodosius II, helmeted, pearl-diademed, cuirassed, facing front, holding spear in r. hand behind head and shield decorated with cross on l. arm. Rev: CONCORDIA AVGG; Constantinopolis, helmeted, draped, enthroned, enthroned, facing front, head r., holding long sceptre in r. hand and Victory on globe in l. hand; beneath her r. foot, prow; in exergue, ANT(Γ?). Ref: RIC X Arcadius 100.
The coins of Elmais are fun to collect and are still very affordable. I have a few that I enjoy playing with occasionally. Fun stuff.
I think that one on the top left is similar to one that baffled me recently: https://www.cointalk.com/threads/pointy-thing-on-a-small-greek-ae-help-please.361665/#post-4567367 Macedon, Thessalonica Æ15 (c. 187 - 31 B.C.) Thessalonica mint Diademed head of Artemis right / [ΦΕΣ]ΣΑΛΟ [ΝΙΚΕΩΝ] Quiver with bow behind, monogram right [and monogram left]. SNG Copenhagen 356; Moushmov 6600; HGC 3, 733. (5.49 grams / 15 mm)
