In the year 284 This Tetradrachm was issued under Roman Emperor Numerian. I am constantly amazed that a coin minted nearly 2,000 years ago can be dated to the year! For that, and much more on this period and coin, including the wisdom of @phistorians please check out: https://coinofnote.com/284-rome-numerian-tetradrachm/
If that hasn't tempted you already, then maybe the threat of my poetry will?
