Identification mark help? Chinese? Club 63

I found this while going through my late uncles estate. I think it may be a cigarette holder but not sure. I need help with the marks. Silver? Silver plated?

Thank you

View that lowest boxed mark upside down and see if it matches the Chinese character for basic Silver (not the pure silver compound mark) here: https://www.925-1000.com/Fkorea_01.html

Thank you. I’ve got a few more photos I think a little more clear.
