Like many other mints, the Royal Mint issues bullion coins in precious metals, having much higher intrinsic value than their face value. Most of these by tradition are measured in troy ounces of fractions thereof, but the mint also introduced metric coins measuring one kilogram of pure metal (they are actually fractionally heavier as a whole, to account for the small amount of other metal in the alloy).
The 1 kg gold coins are denominated as One Thousand Pounds (£1,000), although their intrinsic (bullion) value is much higher than their face value. The coins vary in design depending on the occasion (they are "one-year" types usually issued in parallel with smaller denominations with the same reverse designs).
The coins are legal tender but are not intended for circulation. They are targeted at bullion investors or collectors who appreciate the special editions as pieces of art.
This coin marking the 250th anniversary of the battles of Lexington and Concord is part of the first commemorative issue of the Royal Mint to mark an American anniversary.
The Battles of Lexington and Concord were the first major military campaign of the American Revolutionary War, resulting in an American victory and outpouring of militia support for the anti-British cause. The battles were fought on 19 April 1775, in Middlesex County in the colonial-era Province of Massachusetts Bay, within the towns of Lexington, Concord, Lincoln, Menotomy (present-day Arlington), and Cambridge. They marked the outbreak of armed conflict between the Kingdom of Great Britain and Patriot militias from America's Thirteen Colonies. Although they were relatively small skirmishes, they were historically monumental, initiating the beginning of the American Revolutionary War, they led to the founding of the United States of America.
The reverse of the coin was designed by American sculptor and engraver Michael Gaudioso. |
