I have a silver pendant that I just learned is a little case for stamps. I did some research and learned what the hallmarks mean, but I am not sure that I am right about the date hallmark. I learned that C&N means Crisford and Norris, that the anchor means Birmingham, that the lion means sterling silver and the lower case f supposedly means 1905. This is the part that I am confused about, though, because this pendant is engraved on the back in French, and the date engraved is in 1965. I looked up the date letter hallmark for 1965 online, though, and it is not an f (if the resource I used was even accurate). If anyone can shed any light on this, it would be greatly appreciated (photos attached).
