Not yet. I was looking at one a while ago, though. The Nürnberg 8 ducat would fit, if not for the price tag.
I once had this... umm... whatever it was. It was some kind of Zvingli medal. Looked 18th century to me. Another of these Reformation-themed pieces, I would presume. There were traces of bright luster in the protected areas around the portrait and lettering (which naturally did not show in my scans). Maybe pewter, but maybe it was tin, now that I think about it. So, the chronogram... Let's see... there's M...I... VLD...ICV... VI...LI. Under the portrait, there seems to be: "ÆT 48 AN 1531", so I suppose that means Zvingli was 48 years old in 1531? I sold this piece on eBay later. A person in Germany won it. Then I couldn't find it and had to issue a refund. He was not happy and left me a harshly worded neutral in German. Years later, it has still never turned back up. I wonder if some day I will open a box or drawer and find it. Chronograms make my head hurt. That's probably why I lost this piece. Yeah, that's my excuse. It had nothing to do with desk clutter.
Interesting piece. What you have (had) there sure looks like a trial or old copy of a 1719 Zwingli piece from Zurich (celebrating the 200th anniversary of the Protestant Refromation in Zurich). Zwingli was killed during a battle in 1531. The medal with that obverse had 2 different reverses, one with a portrait of Heinrich Bullinger (another Swiss reformer) and one with various lines of text. I've never seen a uniface version before.
So I am not really a chronogram collecter, per se, but I do collect Reformation pieces, and as wcg noted, there are a bunch of those with chronogram dates. Here is a sampling: Nurnberg, 1650 Peace of Westphalia, ending 30 Years' War (chronogram obverse, numerical date reverse) Schwabish-Hall 2 Ducat, 1717 200th Anniversary of the Protestant Reformation (Chronogram on obverse and reverse AND numerical date on reverse--kinda overkill): Augsburg 1730, 200th Anniversary of the Augsburg Confession (Chronograms on obverse and reverse): Wittenberg 1717, Luther and wife, Catherine von Bora (chronograms obverse and reverse):
Wow! Thanks! I always wondered about that supposed die trial piece I had. Too bad it's lost, but there's a one in a kazillion chance it could turn up again.
I know there are chronogram coins in other languages too, Arabic and Hebrew. I don't have any examples yet, but they're on my list!
Here is my modern chronogram medal; it was minted in 2011, but has the chronogram date of 2017 on the obverse to celebrate the 500th anniversary of the Protestant Reformation (jointly designed by Daniel Harmelink, collector of Reformation numismatic material who clearly knew the history of chronogram-dated material in this genre, and Victor Huster [noted for his distinctively stylized medallic art])
TOURNAI Siege 8 Sols 1708 (when a French garrison was being besieged by Allied troops during the War of the Spanish Succession) Reverse: MONETA /IN/OBSIDIONE (besieged)/TORNACENSI/CVSA (minted in siege of Tournai) The order is a jumble but M+D+C+C+V+I+I+I = 1708
Nice ducat, and, once again, it is a Protestant Reformation piece. I don't know why so many of these particular commemoratives are chronograms, so I'd be interested in anybody's theory.
