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 .999 investment-grade silver. These coins have been produced by the Royal British Mint since 1997 and are eagerly sought after by collectors as well as investors. Each features the beautiful Britannia, who is an ancient symbol of that island nations strength and unity. The exquisitely detailed engraving shows the windblown goddess armed with a trident, shield and helmet. A portrait of Queen Elizabeth II, the worlds longest-reigning monarch, graces the obverse of these immensely popular collectors items.
