This does not seem to have the same rim design as other Rogers Bros Turkey Well and Tree Footed Platters have. It looks close to the 1847 Remembrance Platter, but I do not believe it is from that collection, because the rim is different. This platter is also footed.
The mark on the bottom of the plate reads: "Silver on Copper" and on either side of this are two crowns stamped into it. I read somewhere that F.B. Rogers has a one-crown logo with 18 and 83 on opposite sides, but on this there are two crowns and no date. I searched other collections and patterns of the International Silver Co., but I did not see anything that looked identical. Also, I looked at Reed & Barton's turkey platters but the tops of their trees were not the same.
I am just very confused. I would love to know the real origin of this piece, and if she holds any specific sort of monetary value.
