Western Samoa's Monetary Board was established in 1984 to take over central banking functions from the Bank of Western Samoa, and this note belongs to that transitional period when the issuing authority itself was newly constituted. Thomas De La Rue had printed Samoan currency since the tālā's introduction in 1967, and the relationship was uninterrupted through the changeover.

The P#23 series is relatively short-lived — the Monetary Board was itself superseded by the Central Bank of Samoa in 1984, meaning the window of issue for this authority was extremely narrow. Surviving examples with clean folds are not common precisely because so few were printed before the institutional change required new note designs under the new issuer name.
