Hello, I own two silver sheffield vases made by james dixon and sons in 1904. They have coalport porcelain interiors in dark blue and gold little flowers. They are 21 cm tall and have the hallmarks proving the description I just made. I would like to know what they are worth, and if you are interested what would be an estimated price for them. Ifyou need photographs I`ll be happy to send them by mail. Thank you very much for your help. Yours Sandra MAy
