Could you try putting a solid black or white solid behind it to absorb the light and reduce the mirror affect? I had a really hard time photographing silver at first too. Stand off to the side a bit, near the same level as the piece. Don't try to center it, aim instead slightly off to the side where...

Tunsinia purity mark was similiar on coin or better 1878-1905. I looked it up for you. It is beautiful.

Looks like Russia perhaps, but I'm not positive. Good luck. Did you see the Paul Revere silverplate mark to see if that gives any clues?
