15 000 Riels - Lost Tigers of Cambodia

Cambodia has no wild tiger population left to speak of — the last confirmed sighting of an Indochinese tiger in the country was in 2007, and the species is now considered functionally extinct within its borders. This coin was issued under a conservation awareness program that the National Bank of Cambodia has periodically used since the 1990s to generate hard currency revenue through collector sales, a funding model common among smaller Southeast Asian nations with limited numismatic markets domestically.

The 141.75g specification places this squarely in the five-troy-ounce category, a format that has become increasingly standard for high-relief wildlife issues targeting the international bullion-collector crossover market.
