Medallion of Constantine the Great 4th century AD Gold; diameter 48 mm, weight 43.86 g This piece weighing the equivalent of eight standard gold coins (solodi), was made as a presentation piece. It is unique, differing from other medallions of Constantine in that it shows the Emperor with his four sons. This outstanding example of a 4th-century coin was unearthed when trenches were being dug on the South-Western front during World War I.
