Constantine I MARTI CONSERVATORI (bust of Constantine and Mars) from London (?)

[Victor]

I was going through my CNG wins and found this coin. I am thinking that it looks like Trier (RIC VI Trier 884); but Dr. Malcom Lyne thought London. I am wary of my own judgement in this circumstance and would like to crowdsource this.



Constantine I
circa A.D. 312
21x22mm    3.8g
CONSTANTINVS P F AVG; laureate and cuirassed bust right
MARTI CONSERVATORI; helmeted & cuirassed bust of Mars right


here's a Trier 884

Trier mint IMHO.

For me it is Trier. Already this dubious specimen from my website is much more likely.
