Constantine I - Virt Exercit Gall from Rome

[Spoudaios]

Hi all,
I think this coin is nicely struck with a genuine (?) sand patina.

Obverse: FL VAL CONSTANTINVS AVG
Reverse: VIRT EXERCIT GALL
Half follis
Emissione: end 312 - beginning 313 D.C.   
Weight: 4.32 gr.
Mint: Roma; Officina: Third
RIC VI 360

Note: this half follis is quite heavy (4.32 grams) and I have found on the Internet only one coin that has a similar weight.

Any comment is very welcome.

I have had several with an average weight of 3.4g

[Heliodromus]

Nice coin!

I have one of similar weight, 4.3g, top coin below.

These are actually 2/3 nummus, not 1/2, with the X-VI field marks meaning 16 DC (denarii communes) vs 25 DC nummus. Still, at 4.3g they are almost 50% overweight (closer to 4.57g nummus than 2/3) !

Bottom coin below is a plate coin from Victor Failmezger's "Roman Bronze Coins: From Paganism to Christianity 294-364 A.D", and is an obverse die match to yours.

Thank you both.

Heliodromus, great catch. I did not check Failmezger's book before and, yes, that is an obverse die match. Thanks!
Your coin is very nice too. Heavy, well preserved, minted on a large flan. Congrats!
