| 背面描述 | A Northrop Grumman B-2 Spirit stealth bomber in flight is depicted in the platinum core at center, shown in three-quarter aerial perspective with speed lines trailing to the right. The gold middle ring features six World War-era propeller aircraft — including biplanes and single-engine fighters — arranged in a dynamic circular formation around the core. The silver outer ring displays additional historic aircraft in relief, including early WWI biplanes, flanking the denomination 1 CROWN at the base with the Pobjoy Mint mark. The legend HISTORY OF POWERED FLIGHT arcs across the upper field with the centenary dates 1903 – 2003 below it, commemorating one hundred years of powered aviation. |

Gibraltar's coin program has long leaned on novelty metallurgy to attract collector interest, and this piece is a prime example — three separate precious metal components bonded into a single planchet, requiring precision manufacturing that most sovereign mints wouldn't attempt in volume production. The platinum core alone makes this unusual; platinum is notoriously difficult to strike cleanly, and pairing it with gold and silver rings of differing hardness creates real challenges in die pressure and metal flow.
2003 marked the centenary of powered flight at Kitty Hawk, and Gibraltar was among dozens of minor issuing authorities that produced commemoratives for it.
