1 Mark Sweden

The 1 Mark coin from medieval Sweden was often minted on planchets of varying purity, reflecting the era's inconsistent silver supplies from local mines.

This made it a staple in Hanseatic trade, circulating from Stockholm to Lübeck as a unit of exchange for goods like herring and furs. Struck with simple dies showing the Swedish coat of arms, these coins lacked the intricate designs of later issues, prioritizing durability over artistry. Mintage figures remain unclear; records from that period were scarce or destroyed in later conflicts.

The coin's edge was sometimes crudely hammered, a nod to the blacksmith-like techniques of the time. If you squint, it resembles a poorly made key—fitting for an age when locking away wealth was as common as minting it.
