Often called a "sister coin" to the U.S. silver eagle, these issues are the British equivalent bullion option. Just like our silver eagle, each contains one troy ounce of investment grade .999 pure silver. These £2 bullion issues have been produced by the British Royal Mint since 1997 and are eagerly sought after by collectors as well as investors. Each features the allegorical figure of the beautiful Britannia, an ancient symbol of the island nation's strength and unity.
