This is the first time I have ever seen the Italian Coin Catalog.
Here it is, but there are more than one Italian coin catalogs:

One the pages copied for this forum discussion, for each coin, there is a column for rarity. I assume “C” means “common”, and “R” means “rare”. The coin I have is given the designation of “R2” - what does that mean?

The numista webpage for the KM# 1360/N-3585 coins ends with the 1864-R XIX date. based upon this forum discussion, the date 1865-R A.XIX should be added. At the present time, the only option for an 1865-R XIX coin is to add it to the KM# 1360a/N-38287 Numista web page, and it is possible that some of the 1865-R XIX coins on that page might actually be KM# 1360/N-3585 coins (which the Italian Coin Catalog indicates are more common). Now, it is easy to tell the difference - just check if the obverse legend ends with A.XIX or AN.XIX.
Keen eye about the AN - A thing. Based upon Krause and this Italian catalog I agree the 1865 A. XIX should be replaced from the KM# 1360a coin page to the KM# 1360 coin page.
However it's not always as simple as it looks. Like I've said there are more than one Italian catalogs, maybe there's more information in one of the others why Numista doesn't follow Krause and this Italian catalog. We already know there are plenty of mistakes in Krause, just like there are in Numista, and in this Italian catalog something is wrong too:

When you look at the pictures for the Ag .800 5,71 g. coin, you'll see it's a 1865 AN.XIX, which is not consistent with the description in the year list which says 1865 has A.XIX

And here is another problem: https://www.acsearch.info/search.html?id=5463493
I don't know if auction houses actually weigh every coin they offer or just get the information from a catalog. This particular description says 1865, AN XIX while it's obviously A XIX, so that's not correct, maybe the weight isn't either. But if the weight is correct, it means 1865 A.XIX exists as both KM# 1360 and KM# 1360a and you can no longer determine the type by the AN - A thing.
But to be honest, there are so many web pages about this coin type (https://www.acsearch.info/search.html?term=20+baiocchi+1865&category=1-2&lot=&date_from=&date_to=&thesaurus=1&images=1&en=1&de=1&fr=1&it=1&es=1&ot=1¤cy=usd&order=0) and this is the only one which is not on line with our findings. So it's quite possible they didn't weigh the coin but took the information from the catalog.

One final post on this
I don't think it will be your final post on this.
Sorry to make it so complicated.
There are other mistakes/shortcomings on the Numista coin pages for these types, so I'll contact the Papal States referee and see what he says. I'll keep you posted here.
