Hello Gordon
Yes I have had several of silver ones in my posession, and I have heard of copies, but never had one in my hands...
As for grades of this medal, there are four grades, some says even more!
First grade is gold with enamels, second grade is gold(possible gilded gold), third grade is silver, fourth grade is bronze.
But there are also silvered bronze, and even a nickel one... where those two features I haven't find out...
If I made some mistake in grading, please do correct me!
As for the first grade medal I have seen two of them in the Castelfidardo museum in Italy, and one more in private collection. One of them have two clasps C Fidardo and Ancona, and other two are claspless..
But I haven't find out any of those firstgraders has ever been sold on any auction, so its value is still a ????
I could ask a Vatican museum a few milion bucks for it??
I have heard that they have an extra money they don't need at the moment...
Thank you Gordon for your help, If you could you can post a photo of the silver copy, so people could be aware of it!
Best regards
Joseph
