Commodity Nickel
Its traces can be found in coins and weapons. Nickel was discovered by Axel von Cronstedt, who believed he was extracting copper but instead found a silver-white metal which he named nickel. Initially nickel could only be extracted from the very rare Kupfernickel but later on it would be obtained as a by-product from cobalt blue production.
