3 Koruny

The 1961 Czechoslovak státovka issues — state treasury notes, not central bank obligations — reflect the country's post-1948 monetary architecture, in which the státní banka handled credit functions while small denominations were issued directly by the state. The 3 Kčs denomination is the odd one out in most Western decimal systems, but Czechoslovakia maintained it through several currency reforms as a practical concession to everyday retail pricing under the planned economy.

A print run of just over 12 million is modest for a circulating low denomination, and survivors in fresh condition are less common than the numbers suggest — these were working notes, handled constantly and rarely saved.
