The only one I've IDed so far (not pictured) was a Kingdom of Napoleon 1 centismo from 1807. The shopkeeper thought most of these were older, maybe 1500s from around Italy for many of them. These are in pretty rough shape, but any suggestions as to what some of them might be or what's a good resource to ID them would be welcome. I'm happy to take a better photo front and back of any individual ones by row/column if that would help. Thanks!
