Wedgwood Antique Saucer

This is a nice Jasperware saucer made by Wedgwood in the 19th century - pre 1860. This is way outside my expertise and I just bought them because I don't own an antique example yet. The light blue background nicely brings out the white raised designs all around the rim area. The saucer is of better quality than what I usually see but like I said this isn't really my thing. It is 0.75 inches tall and has a diameter of 4.625 inches. It came with a cup which I am not sure is original to it as the blue on that one is much deeper. The saucer is in perfect condition. It is marked underneath with the impressed WEDGWOOD mark as well as a small other mark that looks like a v. Not sure how to exactly date this but I know if is older than 1860. Maybe someone can help me with this one :) Please email me for more information or other pictures.
