Mercian Kings. Offa, 757-796
The coins of Offa are of great variety in type, of considerable beauty in design, and of better workmanship than most of the Saxon pennies. On the obverse is the name OFFA REX, or REX M, or REX MERCIORN. Reverse, various crosses and other devices and moneyer’s name. Of these upwards of fifty are known, and some of them used Runic letters.
