Hi Sharon,
I have a glass plate which is clear in colour, fluted edge with a grape pattern and it does date from 1925. I have this love for 1920's/1930's ware . As far as I am aware (my brother is an antique dealer) it's not worth shouting about but then again he's my brother - no music/lyrics please!!! Take it to an auction house and see what they say - I would be interested to know too.
