Currently it is the Euro, but before they adopted the Euro it was known as "Slovak koruna"
koruna~
euro
now we have EURO and before that we had SLOVENSKÁ KORUNA
The EURO is Greece's unit of money.
Euro is official and only currency of Slovakia after adopting it at 1st January 2009. Slovak Koruna, previous currency, is not valid since that date.
To be honest, Slovakia was the poorest side. Before 1900's Slovakia and the Czech Republic were known as Czechoslovakia, in 1993 they decided to split up. Czech Republic took most of the land, the money and the fame. Slovakia and the Czech made the Skoda car together but the Czech rep. took the fame, untill Slovakia offered a fair amount of money to be part of the Skoda fame. if you look at a map really closely, you will see that Slovakia has the smallest part of land, and ofcourse, the Czech have the largest. So, technically, to answer the question you asked, you have to find the evidence and decide yourself. Sorry if this answer didn't really help.
