50 Pence - Charles III Concorde; Silver Piedfort

Concorde's retirement in October 2003 came not from technical failure but from a commercial decision by British Airways and Air France following the 2000 crash at Gonesse and the post-9/11 collapse in transatlantic business travel. The aircraft had flown profitably for decades; it was market forces, not engineering limits, that grounded it. The piedfort format — double the thickness of a standard strike — has been the Royal Mint's preferred vehicle for silver collector issues since the early 1980s, lending weight to subjects that might otherwise feel underserved by a single-thickness flan.
