500 Dollars - Elizabeth II Czech Lion

The Czech Lion bullion series, produced by the Czech Mint for Niue, launched in 2016 and rapidly became one of the more commercially successful sovereign-backed gold programs in Central Europe. The one-kilogram and ten-ounce formats attracted institutional buyers and private collectors across the EU, partly because Czech Mint's relationship with Niue allowed for legal tender status without the bureaucratic overhead of issuing under Czech or Slovak authority.

The 10 oz format sits at an awkward price point — too heavy for casual stacking, too common for serious rarity collectors — but the .9999 fineness and Czech Mint's consistently tight production tolerances have kept secondary market premiums stable.
