A bracteate (from the Latin bractea, a thin piece of metal) is a flat, thin, single-sided gold coin produced in Northern Europe predominantly during the Migration Period of the Germanic Iron Age (in Sweden this includes the Vendel era), but the name is also used for later produced coins of silver produced in central Europe during the early Middle Ages. There are also described pieces from the Hun caucases and the Hunnic invasion of India, in the style of Gupta and Roman coinage.
