2009 London 2012 Big Ben £5 Coloured Proof

This 2009 Royal Mint £5 coin was issue around the 11^th July 2009 to 

“Celebrate the 150^th of Big Ben” – Our Parliament Clock. 

The name “Big Ben” should technically only refer to the clock’s largest bell, but has become synonymous with the clock and the tower. The bell was cast in Whitechapel on 10 April 1858. It was first rung in the Great Westminster Clock on 11 July 1859. 

* The Great Clock was started 12 days earlier on 31 May 1859. The quarter bells first chimed on 7 September 1859.
