Hello. Please help me identify that silver hallmark. Thank you.

We'll start with the (primary) list of countries by silver standards having .800 grade (here): https://www.925-1000.com/a_Standards.html

Maybe another shot of that mark in close-up if possible? (Use a magnifying lens/loupe of 10x if you can). Cleaning out a mark sometimes reveals more...cottton swabs work wonders here.
