Coin silver ladies decorative comb, Unmarked

These combs are an interesting look into fashions of the 1850's. This one is 3 1/2" x 3 1/2". It is perfectly plain except for a monogram on the back. The monogram is "SW" for Susan Warner. See photo of the note. It has a small crack to the right of the 5th tine from the left. The crack does not seem to diminish the strength of the piece and would be easily repaired. Ca 1850.
