Constantius II Ambianum Mint Coin [resuelto]

Hi, 

I came across this coin today and have seemed to have gotten close to identifying it but am stuck at the last hurdle. 

What I've found out:

Fallen Horseman Coin

Minted in Ambianum - AMBI 

Possibly - Constantius II

However, I can't find and matches online for this exact mint for this coin. 

It weighs 3g and is 20mm.

Does anybody have anymore information or a better understanding of these coins, please? 

Thanks, 

Tom

The reverse type is FELP TEMP REPARATIO, and the mint is ANBI, the 12th Officina from Antioch

N#333369

Hi, 

Does it matter that that coin is only 2.2g and mine weighs 3g, as well as being 4mm larger? 

Also, the shield is a circle on that one but more of a pointed oval on mine? 

Thanks, 

Tom

Anverse: Constantius II to the right

Reverse: FEL TEMP-REPARATIO

Mint: ANBI - 12th Officina from Antioch

For this specific combination, the OCRE have 6 different types. With small different details, but all in the same AE3 denomination.

The standard size/weight for mid 4th century Nummus is the AE3 denomination, around 18-22mm and 3-3.5 grams.

And for late 4th century Nummus is AE4, known as Minimus, around 9,5-16mm and 0,7-1,7 grams.

Hi, 

Okay, thank you very much!

Baricatra is correct. The type is RIC VIII Antioch 187a, minted under Constantius II at Antioch between 355 and 361.
 

Coins of that specific type do tend to be closer to 16.5 mm in size, but the normal range is 14.5 mm to 19 mm for diameter and 2.1 g to 3.5 g for weight. You just have a particularly large coin, outside of the norm.

I can definitely understand why you might think the mint mark on your coin is AMBI at first. However, only four types of FEL TEMP coins were minted at Ambianum (Amiens), and they all had mint mark AMB. Your mint mark is actually ANΒΙ, where AN stands for Antioch, and the last two letters are Greek numerals. Β is equal to 2, and Ι is equal to 10. Add them up, and they signify the 12th officina at Antioch, where the coin was minted.

As an aside, I wish OCRE would more clearly distinguish the difference between Antioch 187a and Antioch 190 on the respective pages. (The latter type has an M on the reverse.)

Edit: fixed link.

The link is broken. Here it is: https://numismatics.org/ocre/id/ric.8.anch.187a

I tried searching for some more similar ones, but since we have 6 types in the same mint, and among those, some have more than 40 pieces per type, It's difficult to find one in the same officina and dimensions.

Considering their manufacturing process and the enormous number of manufacturing locations for Antioch, it's actually quite "common" to find non-standard pieces.
