1817, Tower Hill: the Royal Mint inaugurates the Sovereign, a 22-carat coin whose dense yellow becomes a British yardstick. Under gaslight, Pistrucci’s Saint George casts a disciplined glow across the city; dealers swear true gold can be “heard” in its colour. Aurum Sovereign borrows that deliberate clarity: a yellow that doesn’t shout, yet cuts through. Optimism on a schedule, the energy of a signature that won’t wait for the meeting to end.
