100 Manat Nakhchivan

Nakhchivan is an exclave of Azerbaijan — physically separated from the rest of the country by Armenian territory — and issues like this one periodically assert that administrative connection through commemorative coinage struck under the Central Bank's authority. The autonomous republic has its own parliament and government but remains constitutionally part of Azerbaijan, a political arrangement that has been a source of regional tension since the Soviet collapse.

At 31.1 g of .999 gold, this is a one-troy-ounce issue, a denomination structure common to bullion-adjacent commemoratives of the 2010s.
