Hello and welcome.

Unfortunately, my edition of the Krause world coin catalogues does not include much information regarding the smaller coins of the Italian states older than 1750; this makes it hard for me to look them up the "easy way". Apparently, newer versions of the catalogue have this information. The NGC and NumisMaster websites also have this information, but unfortunately you need to already know the name of the denomination before you can go looking.
