The Paris Mint said on May 26, 2026, that it would soon start selling solid-gold coins for investment, the first since it quit making Napoleons and Louis a century ago. Four versions of the new Marianne coins will go on sale June 16, ranging from one-tenth of an ounce (3.1 grams) to a full ounce (31.1 grams). (Photo by SIMON WOHLFAHRT / AFP via Getty Images)
