Thank you for a fast reply confirming. I appreciate you also commenting that it is a "great piece of history" to pick up on a vacation. I know nothing about coins or the jewelry shop I purchased it from in Greece. I wanted a nice, expensive keepsake. I grossly overpaid according to what I see the loose coins selling for on the internet. It is stamped 22K on the pendant bezel. Gold is high currently, so I a telling myself the "gold and craftsmanship" boosted the price. I am hoping that I paid only double what it is worth. Add on 20% too for "the memory". Maybe I will get close to what I paid.

I am of Italian descent and was extremely happy to discover this was a Venetian coin. I am also a Christian so appreciate the religious factor as well. Made the coin more special to me.
I appreciate your time and help.
It is a fantastic keepsake that will be passed to my daughters.
