Note: This is my first post, hopefully, I've posted the question in the appropriate forum. This is a silver box measuring W 9 1/2", L 6", H 2 1/2". Monogrammed on the top is the date of November 20th. Monogrammed on the front of the box is 1840 - 1910. On the bottom of the box at one end is stamped 1 2 3, the other end Sterling with a single mark (see photo). On the bottom side of the box is stamped Made for Tiffany & Co. The link below to photos. Thanks
