Ancient guys I need your help please I found 105 pounds (47kg) of coins in two buckets in a garage of a house clearance, silver, copper, coins of all ages from all over the world. I've identified most but found 7 ancients, one is in olive oil for a while. These 6. obverse and reverse. Quarter for size comparison. #1 12.5 grams #2. 12.3 grams I don't know if I have the reverse the correct way up. #3. 3.7 grams #4 2.1 grams #5 1.7 grams #6. 9.2 grams, quite thick.
I can only help with #4 and #5 4 - Severus Alexandar, looks to be Sol walking left, raising a hand and, holding a whip. I can't make out the rest based off your pictures but you can find it here probably: http://www.wildwinds.com/coins/ric/severus_alexander/t.html 5 - Septimius Severus, denarius, Septimius Severus sacrificing over an alter http://www.wildwinds.com/coins/ric/septimius_severus/t.html
#2-- Roman provincial, possibly a Valerian from Cilicia-- like this example from Naumann: CILICIA. Aegeae. Valerian (253-260). Ae. Obv: AV KAI ΠΟV ΛΙΚ OVAΛΕΡΙΑΝΟC CEB. Radiate, draped and cuirassed bust right. Rev: AIΓΕAIWΝ ΝΕWKO NAVAPXIC / ΘQC. Cult statue of Asklepios standing left in tetrastyle temple, holding serpent-entwined staff; eagle in pediment. SNG Levante 1793. Condition: Fine. Weight: 10.83 g. Diameter: 28 mm. Hard to say though given the coin's condition but it is provincial, somewhat look like Valerian (although identifying provincials based on portrait can be very unreliable, and this could even be an empress wearing a stephane) and the general iconography of the reverse fits.
Coin number 3 is a bronze follis of Helena (mother of Constantine I). It was minted in Trier around 324-326 AD. The obverse legend is FL HELENA AUGUSTA, and the reverse legend is SECURITAS REIPVBLICE. Here is mine: Helena, mother of Constantine I, AE Follis (19mm., 2.25g,) Treveri (Trier) circa 326, Diademed and draped bust of Helena right/ Reverse- Securitas standing facing, head left, holding branch; in exergue, STR(pellet-in-crescent). RIC 481. EDIT- Just wanted to clarify that I can’t tell from the photo whether your coin 3 is a genuine version of this coin or a cast fake.
#4 and #5 should be silver but look to be cast copies in base metal. These might be ancient or might be (relatively) modern.
Numbers 4 and 5 might be limes denarii. I recently got one from Severus Alexander that has that "look" to it - it might be a match for No. 4 (TRP XIII): Severus Alexander Æ Limes Denarius (234 A.D.) Rome (?) Mint (imitation) IMP ALEXANDER PIVS AVG, laureate, draped bust right / PM TRP XIII COS III PP, Sol radiate, nude but for chlamys over left shoulder, walking left, rt. hand raised, whip in left hand. RIC 123; Sear 7916. (3.13 grams / 18 mm)
