10 Dollars - Elizabeth II Lady Britain 2016

The "Lady Britain" branding is a marketing construct from a private minting program, not a Solomon Islands government monetary initiative — the country's name appears on the coin by licensing arrangement, a common practice that allows micro-weight bullion pieces to carry sovereign legal tender status while being produced entirely for the collector and investor market. At 0.311 g, this is among the smallest gold coin formats commercially produced, a size made technically viable only by modern die-cutting precision.
