The chemistry behind the new one pound coin

We all know that money makes the world go around, but do you know what goes into it? The new pound coin arrived on 28th March, largely as a preventative measure against counterfeiting.  Take a look at the graphic below for more information about its composition.

Source: Compound Interest

Why the new coin is harder to counterfeit:
  1. 12-sided - its distinctive shape means it stands out by sight and by touch
  2. Bimetallic - The outer ring is gold coloured (nickel-brass) and the inner ring is silver coloured (nickel-plated alloy)
  3. Latent image - it has an image like a hologram that changes from a '£' symbol to the number '1' when the coin is seen from different angles
  4. Micro-lettering - around the rim on the heads side of the coin tiny lettering reads: ONE POUND. On the tails side you can find the year the coin was produced
  5. Milled edges - it has grooves on alternate sides
  6. Hidden high security feature - an additional security feature is built into the coin to protect it from counterfeiting but details have not been revealed
