These are beautiful Tiffany sterling silver tumblers. They would be great for Mint Juleps. The tumblers are marked Tiffany & Co, 925, 25164.  

The tumblers are in excellent condition with no visible scratches. 

They are 3 1/2 inches in height, 3 inches wide at the top and  2 1/2 inches wide at the bottom.

All the dark areas seen in the pictures on the tumblers are reflection from the iphone when taking the pictures.
