The Kidney Head quarter staters are a bit of an enigma. The obverse uses the standard Two Men in a Boat motif used by all the GB-C quarter staters, but the reverse shows a head which is not normally seen on the reverse of a coin (the only other quarter stater I know of with a head on the reverse is ABC 1076, the British “Tincomarus Medusa”).
Their weight suggests that they circulated at the same time as CB-Ca Class 3 to 6 staters which means they were likely minted to pay for the Cimbric wars, and as expected, they are found scattered all over Belgic Gaul and the South East of England. A small number of find spots concentrated in the upper Somme Valley suggests they were minted by the Vermandois tribe, who were a neighbour of the Ambiani.
