1 Dollar - Elizabeth II M-4 Sherman

Tuvalu has issued commemorative dollar coins under Australian licensing arrangements since the 1970s, and by 2017 the program had expanded into themed military hardware series targeting collector markets across Asia and North America. The M4 Sherman was the primary American medium tank of World War II, produced in greater numbers than any other Allied tank — over 49,000 built across multiple manufacturers.

Silver-plated copper-nickel rather than fine silver, which places this firmly in the budget collector tier.
