Dear Sir or Madam,
I am the head of Chemistry in a Scottish Secondary school. One of my senior pupils is investigating methods of determining copper and iron in 2p coins.
We would be extremely grateful if you could supply us with a value for the mass of copper/ % copper in a copper plated steel 2p coin.
