100 Dalasis

The Central Bank of The Gambia introduced this denomination as part of a series refresh that followed a period of significant monetary pressure in the late 1990s, when the dalasi had depreciated sharply against major currencies. The 100 Dalasi was the highest denomination in circulation during this window, making it a workhorse note in a low-banknote economy where high-value transactions were common but banking infrastructure remained thin outside Banjul.

Thomas De La Rue's involvement is unsurprising — the Gambia has relied on De La Rue for the bulk of its currency production since independence. The security specification here is relatively modest for the period, with a plain windowed thread rather than the motion or color-shifting threads De La Rue was deploying on more security-sensitive contracts at the same time.
