Translated from NOS TV in the Netherlands:
The buckle is from the 10th to the 12th century. Typical are the inwardly rolled rank ornaments. The lion’s head with outstretched tongue (buckle thorn) was often used in the Nordic art world, especially in sculptures in churches.
The buckle will be exhibited in the town hall of Oudewater. The amateur archaeologist does not say where he made his discovery. He fears that other people will scour the meadows. Farmers may be affected by that, he says.
