Ceska Republika 1999 20 Kc [resuelto]

I stumbled upon this coin today and have not been able to find any information.  The closest thing Numista's catalog had was a 2000 Korun.  The image on the front is the same as the coin in question, but the back of this coin features a man on horseback.  I'm curious about this coin and would like to know anything about it.  Thanks!
