This is a 4-coin commemorative set minted by the Royal Mint in 1991.

On 7 December 1941, a Japanese carrier based aircraft launched a surprise attack on an important United States military base at Pearl Harbour, Hawaii, therefore precipitating American involvement in World War 2. The attack on Pearl Harbour signalled the extension of the world into the Pacific Islands and to mark the 50th anniversary of this event, the Central Bank of Solomon has authorized the Royal Mint to strike a limited number of four-coin gold Proof collections. 

The set contains 4 coins in the following weights : 1 oz, 1/2 oz 1/4 oz and 1/10 oz.

The coins are minted in .999 purity.

A maximum of 500 sets were produced.
