I found this at a site on Germanic symbology. Do you suppose the coin's
reverse depicts the killing of an Ice Giant by Thor?
Quote:
Footprint: the footprint is a symbol of the god Njord/Nerthus, it may have been derived from the Scandinavian
legend in which the god Thor (Thunar) killed the father of a Frost Giantess named Skadi, as retribution she was allowed to choose one of the gods as her husband, the trick was that the gods were positioned behind a curtain and that she
had to
pick one by looking at their feet, she chose the most beautiful feet hoping that they belonged to Balder, but the god attached to them turned out to be Njord.
The footprint was associated with
fertility and the Vanir (Wanen) gods.
