Reference for Constantine I Follis

[Istinpolin]

Dear Friends,

please help to find a reference number for this type. I have checked everywhere but was unable to find it. The obverse constellation seems to be rare. This is what I got so far.

Roman Imperial, Constantine I, AE Follis, London
4,75g, 22 mm

Obverse: IMP CONSTANTINVS P F AVG Helmeted and cuirassed bust of Constantine I to left, holding spear over his right shoulder and shield on his left.
Reverse: SOLI INVICTO COMITI T-F, Sol standing left, chlamys falling from left shoulder, holding globe and raising right hand. Mintmark PLN.
Reference: ?

I have found the obverse here:

And the reverse is London RIC VI 124

I would highly appreciate help. Thank you in advance

Best wishes

Nice coin!

It's Cloke-Toone 6.02.013, unlisted in RIC. Yours is the 4th specimen I'm aware of, all from same obverse die.
