Anyone out there expert in ancient pottery and porcelain?

I can not find the value for a great pitcher I recently found. It was my grandmothers, and at least 120 years. It is perfect condition. The launcher was made by Mercer Pottery New Jersey, and is mostly white, with floral accents and gold. I have a picture for anyone to see who is interested. There are no figures on the launcher, just the crown and shield logo that says semivitreous' and MERCER.

Are there any numbers or anything else in the room? If you are in the Mercer County area, which is where I am, you can go to David Rago antiques in Lambertville, New Jersey. Every Monday, they give estimates Free. I think the ratings start at noon. You may have seen Mr. Rago on Antiques Roadshow. If the pitcher has any value, it would certainly be able you say. Good luck!
