Help with Silver Plate Marks

Grabbed this silver plate goblet, I thought it might be sheffield silverplate, any ideas?
It has a crown marks, crossed keys and what I think is a G?

 

MrNate, the mark appears to be for:

BIRMINGHAM SILVER CO., INC.
of Brooklyn, N.Y. and Yalesville, Conn.
1932 - present
Silver-plated goods

from:

Not Sheffield Plate. American

 

Based on the mark of Goldfeder, succeeded by Birmingham in 1932.

Please post a video of you drinking from that goblet

 

Boy, that would be fun, Terry.

 

Given the size versus Mr. Nate's hand in the photo and the shape, I suspect this might be one of those "cigarette holders" for a dinner party.

 

I wouldn't drink from it if I was you.

It is most likely a silver plated waste bowl from a tea service.
