100 Dollars

The Board of Commissioners of Currency was established in 1967 specifically to issue Singapore's own notes after the breakup of the common Malaya and British Borneo dollar, a currency arrangement that had linked Singapore monetarily to Malaysia and Brunei since 1953. This $100 was among the first series issued under Singapore's sole authority, with Bradbury Wilkinson producing the sheets at their New Malden works — the same facility handling numerous Commonwealth issues through the period.

Four signature combinations exist across the series run. Lim Kim San signed as the first Chairman; Hon Sui Sen, who succeeded him, appears both with and without the red seal. The red seal variants reflect an internal administrative change in how notes were authenticated, not a reprint or plate revision.
