Sets of circulation coins

Each annual set of circulation coins of the Czech Republic contains all currently valid coins that have not been circulated and were minted in the year of issue of the set. Numismatists are impressed by these sets because they offer a unique opportunity to acquire complete series of rare circulating coins with the same year of mintage for their collections. This is because the common coins that go into circulation are minted in response to the current needs of the state, and thus all nominal values almost never appear in the same year.
