3 Dollars - Charles III Wenceslaus IV

The wood-core bimetallic format used here traces directly to Czech artist and mint-tech collaborations that gained traction in the 2010s, with the Münze Österreich and later private minting houses developing inlay techniques capable of bonding organic material to precious metal under sufficient pressure without cracking. Niue, whose name appears on the coin purely by licensing arrangement with New Zealand, has no connection to the subject — Charles IV of Bohemia, Holy Roman Emperor, who founded Prague's Charles University in 1348 and commissioned the Charles Bridge the same year.

The wood species used in the centre is almost certainly sourced to match a Bohemian or Central European provenance, a detail worth confirming against the original mint documentation.
