For most people, Nova Roma is a LARP: a live-action role-playing game, like a Renaissance Fair. Legio XXI Rapax is their active army. Their online medium now is a Wiki here. For others who are very active in Nova Roma, it is a micro-nation with its own constitution here and a Senate and two issues of coins (see here) (author's collection above). They celebrate Roman festivals and encourage the Roman virtues that we here know so well from the reverses of coins. I was a tax-paying "citizen" for one year MMDCCLVI AVC (2002 CE), with the Roman name Gaius Marius Mercurialis. You can only have so many hobbies at once...
Searching here for "Nova Roma" I was treated to this most excellent history of Alexius Komnenos and John Komnenos. https://www.cointalk.com/threads/a-father-and-son-duo.282682/#post-2496575 ... from which I leapt on my own to the Sultanate of Rum in Wikipedia https://en.wikipedia.org/wiki/Sultanate_of_Rum And the descendants of Romans now living in China https://www.telegraph.co.uk/news/wo...-villagers-descended-from-Roman-soldiers.html Steve Saylor is the author of Roman Blood and many other historical fiction novels. He has a webpage (online store) dedicated to science fiction and fantasy about Rome and the ancient world, largely through alternate histories.
I do not understand your comment. The coins are struck, not cast. Do you mean that they are out of stock? I bought mine, 20 of them, actually, but a long time ago.
