Sierra Leone, Nocturnal Wildlife, Pygmy Hippo, Bush Baby, Badger, Duiker, $1, 2008. 4 Coin Set. These four One Dollar legal tender coins were issued under authority of the government of Sierra Leone in 2008. The four animals depicted are the Pigmy Hippo, the Bush Baby, the Honey Badger and the Duiker. The cupro-nickel crowns were infused with a die that makes the metal appear as a gun-metal gray color, an interesting touch considering the animals depicted are all nocturnal.
