1 Dollar - Elizabeth II Data

Niue's dollar-denominated silver issues exist because of a 1990 treaty arrangement granting the island's government full authority to produce legal tender coinage despite New Zealand managing its external affairs. The resulting flood of licensed collector pieces — most tied to entertainment properties or novelty themes — has made Niue one of the most prolific small-nation minting programs of the past three decades, with the Royal Mint, Perth Mint, and various private refiners all producing under its authority at different times.

Without more specific series data, little else can be confirmed for this particular piece.
