I could give you lots of info on Rogers, Smith Co, but basically they were located in New Haven between the years 1862 - 1877, they moved around a bit and was all part of the great gobbling up of silver Co. Based on the marks it would fall into that date frame. The really unique ones can warrant a pretty good price, The range you have selected. However keep in mind you mentioned some damage. Most collectors are really picky about the condition of a item. I have sold a few pots and the ones with only a small amount of damage, I was hard press to get even $20.00 for. Lots and Lots of silverplate items and compitation is extreamly high, seems everybody nowdays has inherited their Grandparents set. You item is for sure a fancy and nice pot, but damage will chop the price alot. As mentioned if that monogram on the pot has some historical story then it will Add value, without any monogram or marking as such really only hurts the value even more. I do wish you luck on the sale of your item, but I think you are looking at maybe $75.00 max. IMO Thanks for posting
