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 nummi, a new denomination of coinage, to replace the older and devalued coinage system. This coin, in particular, is from the Constantinopolis mint and has a unique Type ✶M✶ designation, indicating that it was produced during Justin's reign (518-527 AD).
