Peruvian 925 Silver Tea Set

I’m looking for some information regarding my Silver set
It’s a XX Century Peruvian set marked on the back 925 plat Ind Peruana follow by a star sign and a C in the middle. My mother buy this Set in Peru on the 70’s
I would like to know what could be today’s price and the meaning of the star and the c IN THE MIDDLE, ITS PROBABLY CAMUSSO?

I know this is an old post.
I’m listing Camusso and trying to find the value.
I think all Camusso sets are marked Camusso, and with a flag.
