Indeed, I know that there are a few Viking Styled Stackers, on IG, can consider the Valkyrie as the money of Valhalla and they like BIG coins.
I can presume that a Valkyrie silver will afford a Warrior a Bottomless Horn of Valhalla Mead drink. According to the mythology the Valkyrie personally serve the Warriors their drinks.
The design fits the Pirate Stacker too.
