$10m coin goes on display in London

The world's most valuable coin, believed to be the first ever silver dollar struck by the US Mint, is going on display in London.

The coin was bought three years ago by a private collector for $10m (£6.9m). It is dated 1794 and is thought to have been handled by George Washington himself.

Nicola Stanbridge, has been to see it.
