Selwerd is now part of the city of Groningen, the Netherlands. From around 1310 to around 1350, the lords of Selwerd, hereditary
prefects of the bishops of Utrecht in Groningen, produced coins in Selwerd. Adolf van Gronebeke, as a pretender, minted coins
in his own name at Selwerd in 1356–1357. It is also possible that the coin bearing the inscription MONETA WOVLSV was struck
by the lords of Selwerd.
