Roberta di Camerino purse date?

[wire9vintage]

I was thrilled to find this little bag recently. It's about 7 inches tall and wide. You open it by pulling down on the little charm. Can you help me with a date and also what the letter(s) on the back of the charm is/are? It's not like the "R" on her pieces I'm finding online.

Thanks all!
Elizabeth

Stunning! Could it be 60s, I wonder?

It looks 60s to me.
