10 Dollars - Elizabeth II Neuschwanstein

Neuschwanstein, commissioned by Ludwig II of Bavaria in 1869 and never finished during his lifetime, became state property almost immediately after his mysterious death in 1886 — and was opened to tourists within weeks of his drowning. The Solomon Islands issued this miniature gold piece as part of a broader series of small-denomination bullion-adjacent collectibles targeting the European novelty market, where Neuschwanstein's image carries enormous commercial pull.
