100 Francs Dresden Zwinger

Niger has issued a long-running series of miniature gold pieces bearing famous architectural subjects, with the Dresden Zwinger appearing among several European landmarks licensed for the program. The Zwinger itself was commissioned by Augustus the Strong of Saxony in the early 18th century, built not as a fortress despite its name but as an orangery and festival ground — a distinction that still surprises visitors today.

At 0.5 grams, these were never intended for circulation. They trade almost entirely as bullion-adjacent collectibles, their numismatic premium resting wholly on the series concept rather than any monetary history.
