I was cleaning out my uncles house and found two sets of eight silverware. The stamp on the on the silverware says 1847 Rogers Bros. Warranted 16 DWT. The pattern on the handles look like a crest and on both sides of the crest is a vine, attached to the vine is an oval with a flower inside it, an attached to the oval is three bell flowers. I haven' cleaned them yet, but the look like a gold color, and they do have some weight to them. Can you tell me the pattern, the age and the value? Thanks Patti Mangracina
