1/4 Penning

At 0.014 g, these are among the smallest silver coins ever produced in medieval Europe — cut or hammered to a fraction of an already diminutive penning at a time when Norway's monetary economy was thin enough that fractions of fractions still had practical transaction value. Coin production under the Norwegian crown in this period was loosely administered, with minting rights exercised across several ecclesiastical and royal centers whose output is difficult to attribute precisely. Schive's attribution remains the principal reference, and individual specimens resist firm mint assignment.
