The Guardian reports that a hoard of ancient coins was discovered by a pair of metal detectorists in the Netherlands, in an area where Roman troops returning from Britain may have landed. The coins were placed in a cloth or leather pouch and deposited in a shallow pit in a swampy area. The hoard is made up of 44 gold staters bearing the name of the Celtic king Cunobelin, who ruled in southeastern Britain from A.D. 5 to 40. The hoard also contains some 360 Roman coins, including 72 gold aurei, and 288 silver denarii dated to between 200 B.C....
