This was sold to me recently as a Quattrino of Benedict XIV, 1750 Weight is 2.25 g, about 20-21 mm diameter. Price was $6 so I'm not out for much. I looked it up online and can't find an exact match. Here's the 1750 Papal States quattrino on Numista. The inscriptions on mine are a little different. I think mine says: ob: BENE XIV P rev: PORTA SANCTA (holy door) I think the door is a reference to the Jubilee year of 1750. Benedict XIV was pope from 1740-58 The lack of an explicitly stated denomination (it's a little heavier than the 2.1 g I would expect for a quattrino) and date (papal year or AD) are bugging me. I wonder if it could be a contemporary privately issued copper token. The version of the Papal Arms looks like it might be a regional issue from Gubbio. Krause lists a 1750 Quattrino from Gubbio as a "holy year issue" with no image. I can't find it on Numista for that year at all. Any suggestions welcomed.
I think you may be correct. I found this one on AC search but it is dated. Possibly a token based on this coin. https://www.acsearch.info/search.html?id=478468
Thanks for the info. That one looks almost identical to the one I linked on Numista, although in better condition. Here is a side-by-side comparison: Left: Gubbio 1747 Quattrino Center: My coin. 1750 Gubbio Quattrino? Right: The 1750 Papal States Quattrino from the auction you linked. If you look at the shape of the shield at the bottom, mine looks a lot closer to the Gubbio version than the regular Papal States version. Unfortunately, Krause has no image of the Jubilee Year 1750 Gubbio quattrino, though it does mention it existing. I haven't found any images online at the usual sites. But that's my best best guess. Or failing that, some private token issue closely modeled after the Gubbio quattrino.
Having just done a cursory glance, I believe your coin is indeed a Quattrino from Gubbio. The shield is the same, it’s definitely a holy year issue, and there’s only one holy year for Benedict XIV, 1750. Very interesting!
Gubbio: I walked through that town on my pilgrimage to Rome following the historic Way of St. Francis!
