Sceatta

Common currency in Redbad's Frisia was the 'sceatta'. From 680 CE onwards, following Frankish practice, these tiny silver coins were minted in large numbers in the Anglo-Frisian area. It cannot be understated that these coins are much, much smaller than modern coins, with a diameter of barely a centimeter.

In an 11th century Oldfrisian text are possible references to Redbad minting coins, a sign of wide reach of influence and highly organised structure of rule. There is no doubt these are references to the sceatta, the standard Frisian coin at the time, which means Redbad must have had his own coinage in circulation.
