150 Dollars - Elizabeth II Lady Diana

This issue is one of a wave of high-weight commemorative silver pieces struck by Pacific island nations — Solomon Islands among the most prolific — whose mint relationships with private European producers have generated an enormous volume of collector-market bullion disguised as legal tender. The 1,500-gram specification places it firmly in the "kilo-and-a-half" format favored by producers targeting the display-case collector rather than the numismatic market.

Diana died in Paris in August 1997. Twenty-five years of posthumous commemorative issues across dozens of issuing authorities have made her one of the most merchandised figures in modern world coin production.
