WWII COINS gathers 150 authentic coins struck between 1938 and 1945, an era shaped by war, scarcity, and industrial change. Issued by nations involved in World War II, these coins moved through collapsing economies and shifting political realities. Minted in copper, bronze, gold, silver, brass, zinc, aluminum, steel, and emergency alloys, each piece reflects choices forced by conflict. Metals were redirected to weapons, symbols adjusted, and designs simplified. The material itself carries the mark of war. Once everyday currency, time turned these coins into historical artifacts. Each followed its own path across hands and borders, shaped by survival. Inscribed as Ordinals on Bitcoin, this collection preserves 150 coins as a permanent digital archive. As metals erode and systems fade, circulation becomes memory and preservation becomes permanence.
