5 Dollars - Elizabeth II Vivat Regina: 5/6

Issued as the fifth piece in a six-coin series marking the 90th birthday of Elizabeth II in 2016, this coin arrived at a moment when the Queen had recently surpassed Victoria as Britain's longest-reigning monarch — a record she crossed in September 2015. The Solomon Islands, a Commonwealth realm with Elizabeth as head of state, was among dozens of issuing authorities producing commemorative silver for the occasion.

The "Vivat Regina" title itself is the Latin acclamation traditionally used at coronation ceremonies.
