Tiffany & Co. 1837 Concave Disc Pendant Necklace

Purchased in 2007 on Tiffany & Co. Canada online. Unable to retrieve my account info since it was a long time ago. This is an oldie but a goodie, no longer in production. Polished and cleaned, expected signs of wear due to the nature of the metal and minor dent along the edge right below letter “C” on the pendant yet unnoticeable due to the position and shine on metal. In its original box, not perfect, as good as it gets. The necklace is 16” chain with 15mm diametre unremovable pendant. 925 sterling silver. See all photos and video.
