In 2002, North Korea issued a series 12 coins, eight with animals and four with planes, trains, and ships. There are 100 chon to the won, which makes the denomination of these coins quite small. I doubt these were intended for circulation, but I have included them anyway.
The only place you would find a hippo in North Korea would be in a zoo.
All coin images in Daniel's Coin Zoo are from my personal collection. I collect, research, and personally photograph every coin displayed on this site. PLEASE do not take my images without permission. If you would like to use any coin image you see, just ask me. Thank you.
