Mystery roman Coin!

[Dave R]

I have this coin I think it is Roman British maybe Hadrian!  The bust is facing left which is unusual, also where it should say SC at the bottom it looks like LC!  Looks like Britannia on the other side!

Any ideas what it is?

Here is the other side

[Oscarius]

Constantinopolis City Commemorative, SLG, 2nd officina.

Also minted at 1st officina, PLG.  SLG seems to be less common. IMO

Oscarius forgot to mention LG = Lugdunum (Lyons) which is where the coin was minted. The reverse is Victory holding a spear and a shield.

Thank you for all your help.  : )

Any idea who the Emperor is?

The obverse shows the city personification of Constantinopolis

Just to clarify it for you, Dave.
There are two issues of this coin from Lyons with the PLG mintmark (P meaning Primus = officina/workshop 1).

One has the obverse break CONSTAN-TINOPOLIS
which is RIC VII Lyons 241, rated R1 (rare, but not all that rare), struck in 330-331 AD.
An example of this coin (sorry it's a bit dark) is here:

The other has the obverse break CONSTANT-INOPOLIS
which is RIC VII Lyons 273, rated R4 which is very rare.

I don't have an example of RIC 273 on wildwinds (anyone got a clear one?). There is a coin on Alex's forum gallery described as RIC 273 but if you look at the obverse break, you will see it is a 241.
Dave: perhaps you can have a close look at the obverse to see whether you can make out the last letter at top letter and the first letter at top right.

Oops. Fixed.

Thank you helvetica you really nailed it down

My 1 Million candle lamp has died on me but the first section does look like CONSTANTand the second INOPOLIS very impressed, have to re-charge Lamp and double check it.

After a second scan I can now definitely say it is CONSTAN-TINOPOLIS
