50 Euros Spirit of St Louis, gold

Issued to mark the 90th anniversary of Charles Lindbergh's May 1927 transatlantic crossing, this Monnaie de Paris commemorative belongs to a recurring aviation series that has drawn consistent collector interest in France. Lindbergh's 33.5-hour solo flight from Roosevelt Field, New York to Le Bourget — where an estimated 100,000 spectators had gathered despite the late hour — cemented a particular Franco-American cultural moment that French mints have revisited several times.

The 7.78g fine gold specification places this squarely in the quarter-ounce category, a format the Monnaie de Paris has standardized across much of its modern commemorative gold output.
