Antique Mead & Robbins Triple Silverplate Coffee Urn Pit

Hi, I am new to the site and have a certain antique piece that I believe is quite rare. I was wondering if anyone could tell me the approximate worth of this pitcher/coffee pot or urn or if there is anyone that I could contact in regards to it. It is a triple silverplate coffee urn or pitcher that is marked Mead & Robbins on the bottom Phila. I will try to upload pictures, but I have problems getting my camera to work half of the time. I know John Mead was one of the first people to silverplate in this country and that the date of the piece is probably the late 1800’s, like the 1880’s. Thank you to whoever can help me!
