Filthy lucre takes on a whole new meaning with the new 1-euro and 2-euro coins. A recent study concludes that the coins release up to 320 times as much nickel as European standards permit for prolonged contact with the metal - a common skin allergen. The culprit is the anodic action between the coin's double nickel alloy construction. A 40 mA current flows between the two alloys at the interface. "It's like a mini-battery," said one investigator. The current leads to corrosion and the release of nickel ions.
