I also want to add that remember that the centre is a security feature. Tilt the coins and in the right angle you will see a pattern appear in quite a distinct way. Fakes will not light up like that. Unfortunately The Royal Mint decided to rid the £2 of this feature when they changed the design, but this latent image feature exists on the new £1 coin, just under the Queen's head (where a '£' and '1' light up in different angles)
