Nummus - Constantinus I SOLI INVICTO COMITI, crescent-star, PLN, Londinium

RIC VII 149 places this issue in the reorganized London mint's output following Diocletian's monetary reforms, but by 318 the mint was operating under Constantine's direct authority after his defeat of Maxentius at the Milvian Bridge in 312. The PLN officina mark confirms the first workshop. London's mint was among the most politically sensitive in the western empire — Constantine used it to supply the Rhine frontier armies, and its coinage carried deliberate ideological weight at a moment when Sol Invictus still competed with the emperor's nascent Christian sympathies.

The London mint was closed permanently around 325 AD, making this among its final decades of production.
