2 Dollars - Elizabeth II Tu-144

The Tu-144 holds the distinction of being the first supersonic passenger aircraft to fly, beating Concorde to that record by nearly three months when it took to the air on December 31, 1968. Its commercial service history was brief and troubled — a fatal crash at the 1973 Paris Air Show, likely caused by evasive maneuvers to avoid a French chase plane, effectively ended Western confidence in the program. Aeroflot operated the type on the Moscow–Alma-Ata route for cargo and mail from 1975, with passenger service running only from November 1977 to June 1978.

Niue has issued commemorative silver rounds under its name since the 1990s, functioning largely as a bullion-adjacent collectibles platform rather than a sovereign currency program in any functional sense.
