10 Dollars - Elizabeth II James Cook Discovery

Cook's 1568 "discovery" of the Solomons was, in reality, the islands' rediscovery — Álvaro de Mendaña had reached them in 1568, then spent over two centuries failing to find them again on subsequent Pacific voyages, a navigational embarrassment that delayed European re-contact until 1767. The Solomon Islands themselves were not definitively charted by Cook; much of that work fell to later expeditions.

The 93.3g format places this squarely in the three-troy-ounce collector category, a weight class that became fashionable among Pacific island issuing programs in the late 2010s specifically for large-format colorized or antiqued presentation pieces marketed to the European collector market.
