10 Dollars - Elizabeth II Czech Lion

The Czech Lion series, struck for Niue by the Czech Mint in Jablonec nad Nisou, has become one of the more commercially successful bullion programs to emerge from Central Europe in the past decade — unusual given that neither the issuing territory nor the minting country has any historical monetary relationship. Niue's arrangement as a Pacific island nation under New Zealand's realm makes it a convenient licensing vehicle for foreign mints seeking legal tender status on collector bullion.

The 5 oz format places this squarely in the investment-grade bullion tier rather than the pure numismatic one.
