The most splendid example is the Anastasius Platter, a large decorated platter that bears the reign stamp of Anastasius I, who ruled 491-518 AD. This was basically a control stamp guaranteeing the purity of the silver, something you still see on good silver today. Here are some shots of this work of art courtesy the British Museum.
By the time of the Sutton Hoo burial in the early 7th century, this platter was already more than a century old. so it certainly had time to make it all the way to England. The Byzantine Empire was famed for its power and artwork, and even as far away as England, people craved to have something from its workshops.
