This is a silver cup that’s been in my family for at least 75 years. There are marks on the side, see the photos, one of which is “1811” and the other looks like it was inscribed by hand, a calligraphic initial or similar. The cup may not be 90+ as the patina has reddish blotches.
I’d love to know more about it.
Thanks!
Thank you, that small indent could be something or nothing !!!

I have pieces with what I thought were just tiny indent marks that turned out a form of hallmark, tiny french eagle head on a thimble turned out to be 18ct gold instead of what I thought was brass, tiny Egyptian punch marks on other gold and silver pieces at very close magnification
