Sierra Leone – Mountain Gorilla – $1 – 2011 – Brilliant Uncirculated Crown – The Mountain Gorilla (Gorilla beringei beringei) is one of the two subspecies of the Eastern Gorilla. It has a robust build with long, muscular arms, a massive chest, and broad hands and feet. It is the hairiest race of gorillas; its long, thick black hair insulates it from the cold of living at high elevations. There are two populations, one found in the Virunga volcanic mountains of Central Africa, within three National Parks: Mgahinga, in south-west Uganda; Volcanoes, in north-west Rwanda; and Virunga in the eastern Democratic Republic of Congo (DRC). The other is found in Uganda’s Bwindi Impenetrable National Park. As of Spring 2010, the estimated total number of Mountain Gorillas worldwide is 790.
