A bigger, clearer photo of the dish would be interesting. I agree with the likely hand made nature of the piece. I am not sure I have seen this kind of thing in glass inside churches. I would worry about coin noise and damage. I was wondering if it could be a container for some kind of folded piece of paper, club voting system. If so, a bowling committee, golf committee, masonic, etc... is equally possible. It looks very British. Maybe a clear photo of the base of the glass and general photo of the bowl will suggest a country of possible origin....
