50 Dollars - Elizabeth II Babel II

Tuvalu has no domestic gold reserves and no meaningful monetary need for high-denomination bullion coinage — these pieces are produced under licensing arrangements specifically for the collector market, with the Australian government holding responsibility for Tuvalu's currency under a 1976 agreement. The "Babel II" designation places this within a themed bullion series rather than any circulating monetary program.

At 15.55 g of .9999 fine gold, this is a half-troy-ounce piece, a format that gained traction among Pacific island issuers in the mid-2000s as bullion premiums on fractional gold climbed.
