Interesting fact

One interesting fact about this coin is that it features an image of Justin I, who was the first Byzantine Emperor to introduce the nummus, a new denomination of coinage, to replace the older and devalued coinage system. This coin, the 40 Nummi, was part of that new system and was widely used throughout the Byzantine Empire during Justin's reign.
