The most famous superheroes of the DC Comics publishing house are associated in the Justice League. Flash is one of their founding members, therefore, a special "coin note" - a coin in the form of a banknote made of silver was dedicated to him.

Man of Steel, last son of Krypton, Kal-El, Clark Kent, Superman. Beneath a number of names lies the most powerful being on planet Earth. The very first superhero is faster than a bullet fired and stronger than a locomotive, has frosty breath, fiery gaze, X-ray vision and perfect hearing, and last but not least, he can fly. It is paradoxical that Superman, who is the embodiment of the noblest human ideals - truth, compassion and justice - is in fact an alien sent by his parents on a journey through space to escape the destruction of his home planet.

The reverse side of the "banknote", created at the New Zealand Mint, presents two depictions of Superman inspired by its cinematic appearance - one colored and the other engraved - along with the coat of arms of the El family and the JUSTICE LEAGUE logo. The obverse side then bears the necessary attributes of the issuer, which is the island of Niue – i.e. the name and portrait of Queen Elizabeth II, the nominal value of ONE DOLLAR (NZD) and the year of issue 2018.

The complete six superheroes can be stored in the collector's album that was an integral part of Batman's issue.
