1 Dollar - Elizabeth II Princess Diana

Issued the same year Diana died, this Niuean commemorative was one of hundreds of similar pieces flooding the market within weeks of the August 1997 crash in Paris. Niue — a self-governing territory in free association with New Zealand — had by the 1990s become a reliable vehicle for foreign coin marketing firms producing commemoratives with minimal sovereign involvement. Most of these pieces were sold through mail-order and television shopping channels rather than through any numismatic trade.

Collector demand collapsed almost as quickly as it appeared. The secondary market remains saturated.
