100 Dollars American Express Travelers Cheque

American Express travelers cheques were technically not banknotes but functioned as a global quasi-currency for decades, accepted more reliably than personal checks and, in many countries, more readily than foreign cash. De La Rue's involvement gave the series credible security production — the firm had been printing currency for colonial and sovereign issuers since the mid-nineteenth century, and AmEx leveraged that institutional weight deliberately.

The 1982–1993 date range spans the peak and early decline of the travelers cheque market. By the early 1990s, credit card acceptance abroad was eroding demand sharply. Uncashed cheques from this period remain a known liability on American Express's books to this day — legally, they never expire.
