Gold coins the classics.
The classic gold coins — bought and sold — at Helvetica Exchange, Rue Pierre-Fatio 19, 1204 Geneva (Rive district) — prices follow the live market, premiums displayed, no separate commission. Monday–Friday 08:30–18:30, Saturday 09:00–17:00. Reserve and your rate is held for 3 hours during opening hours; ID from the LBA thresholds.
Coins are gold with a face. The Swiss Vreneli 20 francs and the French Napoléon (6.45 g of 900 gold each) remain the most familiar steps; the British Sovereign, the Krugerrand and the Maple Leaf complete the international ladder to the full ounce. Each coin is weighed and read before you, premiums displayed honestly — strong-premium pieces behave differently from bullion, and we tell you so. We buy back in both directions at the posted price, whatever the origin. A collection or an inheritance deserves the lounge: bring the case, we will take the time.
