This is a vintage English sterling silver OXFORD ingot fob charm pendant. It measures 7/8" tall with the bail ring by 3/8" wide by 1/8" in thickness and weighs a solid 8 grams and tested as 925 sterling silver. There is a hallmark on the back that I am not familiar with and believe that it is quite old. This would make a nice addition to a necklace or bracelet perhaps a key ring. Also, an added plus if you attend the University of Oxford.
Thank you for looking!
