I found this carnet de bal that has a slightly unusual punching. The silversmith's mark has all the characteristics of a French mark, while the guarantee mark is a mark of the Papal State in use from 1817 to 1860.


The marks are very small and it is very difficult to obtain a good image.
The silversmith's mark, in a lozenge, has as its first letter a V, in the center a Jerusalem cross that has four dots in place of the four small crosses, then another letter that looks like a P, but could be an F or something else. It cannot be deciphered with certainty even with a very powerful magnifying glass.
Can anyone identify it?
Thanks for attention
Amena
