Help... I've got 6x Cavalier silver on brass goblets (unboxed) made in uk.... but they are the Mickey Mouse Golden Jubilee edition (1928-1978) with Walt Disney Productions mark on base ... I have searched the web and can only find one photo but no info! I'm eager to know where to find out about them, if they are worth anything, where I would go to sell them. Thanks for taking time to read this
