| Additional information |
The inclusion of titanium in a predominantly gold alloy is not decorative whimsy — it produces a measurable color shift toward a slightly warmer, more rose-adjacent tone compared to standard .999 fine issues, and creates a surface hardness that resists the micro-abrasions typical of softer high-purity gold coins. The Solomon Islands has used this alloy approach for a small run of commemorative issues, all struck by external minting facilities under licensing arrangements rather than any domestic production capacity.
The name "Autitium" refers to the Latin-derived term for gold used in certain modern commemorative branding — worth knowing, as it appears across several Pacific island issuer programs and can cause cataloging confusion when cross-referencing series.
