I have about a dozen that I bought while researching the article. Here is one of the best: Thibault III Poey d'Avant 5978. Rabbi Shlomo Itzak known by his monogram, RASHI. Champagne was a home to Jewish scholarship. Note that the Arthurian Legends were composed by Chretian of Champagne. Somewhat odd, you know, to call yourself "Christian" in a county of, well, Christians, unless, maybe there was another story there...
After reading the OP by @FitzNigel I added a denaro provisino from the Roman Senate to my want list of non-English medieval European coins. The stars finally aligned and I pulled the trigger on one that was fairly inexpensive on Vcoins. Thanks FitzNigel for inspiring me to add new coins to my collection and expanding my interests. Despite what Mrs. TheRed thinks ( "it might be the ugliest coin in your collection") I'm really pleased to have added it.
