On the reverse is

       
     
   

I think that it reads θεοτοκε βοΗθει τιβεριω  = Theotokos, help Tiberius and dates to the 7th or 8th Century.  Have I gotten the age and identity correct?  Pogh_poor

Gert , Thank you for your reply!  I looked  through the Dumbarton Oaks collection and somewhat surprisingly found no seals of any τιβεριω other than the Emperors Tiberios I Constantine,   Tiberios II Constantine and Maurice Tiberios.  Especially given the historical nature of the name Tiberius in the Roman Empire.  Have you seen any seals with τιβεριω?  Pogh_poor

It is an uncommon name, but it is attested for a number of individuals, on seals and in other sources. Zacos col. has none, but Seyrig col. has a bilingual seal of a Tiberius (no. 354). No doubt you will find more in the published works.
