20 Dollars - Elizabeth II

Bermuda's 1970 gold issues marked the island's transition to decimal currency, which took effect on February 6th of that year — replacing the pound system that had been in use since the 17th century. The decision to issue commemorative gold coincided directly with decimalization, not with any royal visit or anniversary, making this a purely monetary-event piece rather than the ceremonial issue it is sometimes mischaracterized as.

The .917 fineness places it in the traditional crown gold standard, consistent with British sovereign coinage practice.
