1 Dollar - Elizabeth II Mumbai

This piece belongs to a wave of novelty collector issues produced for Pacific island nations whose central banks license their names to private minting operations — in this case almost certainly struck by a European or Indian contract mint rather than anything connected to the Solomon Islands themselves. The Mumbai tie is geographical theming, not a mint of origin. Garnet dust as a surface treatment became fashionable among bullion-adjacent collectibles in the early 2020s, borrowed from the gemstone coin segment that had been expanding since roughly 2015.

KM# 1025 suggests a catalog entry, not a circulating issue.
