This cup-shaped gold quarter stater - a Lindsey Scyphate Star Type - is one of the rarest gold coins struck by the Corieltavi of Lincolnshire, a fact which can easily be missed at first glance. The clues to its great rarity are clearly seen on its concave reverse: the ringed-pellet at each end of the reversed S-shape (not dissimilar to the double-headed serpent to be found on enamelled dragonesque brooches and the Ecenian Bury Diadem silver coin) and, more unusually, the five-rayed star each side of it. Only two other Star Types are known in the Lindsey Scyphate series, "one of which is holed and flattened!" exclaims Dr John Sills. This gold coin is not only excessively rare. It is also extremely fine, as sharp as the day it was minted 2,000 years ago; 100% complete with none of the usual chips normally found on such coins.
