Couple find £6 million treasure in US

A couple that found a stash of gold coins in California, have found out the treasure could be worth as much as $10 million (£6m).

They found 1,427 rare coins that date from 1847-1894.

Experts say the coins were never circulated and are in mint condition.

The unnamed couple found them buried in rusting metal cans under a tree while on a walk last April.
