Identify makers mark? Help please!

Can anyone tell me anything about this cup? Maker? Value? Thank you!! I appreciate all of your expertise!!

The 800 means it’s 80% silver, a common silver standard in Continental Europe. I am not familiar with the other marks, but I’ve found this site a good research site for looking them up here
. If I were to hazard a guess I’d say German, but it could be quite a few other countries. I don’t think it’s French.
