Louis The Pious 'Temple' Penny or Denier
Within the inner circle on the obverse is a cross pattee with pellets in the angles and the surrounding legend on this side reads H LVDOVVICVS IMP. The Ludovicus referred to in the legend was known as Louis the Pious (814-840) and was a fairly early member of the Frankish Carolingian dynasty, which was the successor to the Merovingian dynasty.
On the reverse is a stylised building, which is meant to represent the façade of a temple. The legend on this side reads +PISTIANA RELIGIO. The coin is a silver denier and was probably struck at a mint situated at Melle.
