In this show Gordon shows Gary an incredibly special and unique coin he recently found on the banks of a river in Buckinghamshire. It’s believed to have been struck in the name of King Athelstan. Gordon believes this means the coin belongs to the Viking king, Guthrum, who changed his name to Athelstan after losing the Battle of Edington to the mighty King Alfred the Great. However, because the coin is unique the experts struggle to confirm this fact; there’s a chance the coin could have been made in the name of the Saxon King, Athelstan King of all England, instead.
