Byzantine ? Ae Coin For Identification, Please

I think it is Heraclius and Heraclius Constantine Follis overstruck on a follis of Phocas


you can see ANNO on the right side of your first pic and the x's underneath

Thanks very much. I can see now that the ANNO on the upper image belongs to the understrike.

However, the writing that I can see on the overstrike to the left of the left-hand figure (the opposite side from ANNO) seems to say JVN(or R)NI. There seems to be a crude J on the top of the left-hand figure.

On the other side, I can see ANNO to the left, a big M, a B underneath, CON in the exergue, The right hand leg of the M might be an upside down you or the regnal year might be
II
II . Is that possible ? If it is, the left hand bottom I seems cruder than the rest.

Yes, thanks very much.
