100 Dollars New Security Strip

The 2023 issue updates an existing design rather than introducing a new one — the "New Security Strip" designation in the series title confirms this was a targeted security upgrade, not a general reprint cycle. Thomas De La Rue has held the Solomon Islands printing contract for decades, and incremental mid-series security enhancements of this kind are now standard practice for Pacific island issuers working within tight procurement budgets.

Solomon Islands high-denomination notes have historically been low-volume print runs given the country's small population, which keeps genuine circulated examples relatively scarce in the secondary market even shortly after issue.
