100 Dollars - Elizabeth II RMS Titanic

The Solomon Islands has become a prolific issuer of large-format commemorative gold for the numismatic market, and this Titanic piece fits squarely in that commercial tradition — legal tender in name, collectible in practice, never intended to circulate. The RMS Titanic sank on April 15, 1912, after striking an iceberg at approximately 11:40 PM ship's time, with 1,517 lives lost.

The wreck was located by Robert Ballard's expedition in September 1985 at roughly 3,800 meters depth, some 370 miles southeast of Newfoundland — a discovery that reignited public obsession and the commemorative market that followed.
