100 Pounds Sterling

The National Commercial Bank of Scotland was formed in 1959 through the merger of the National Bank of Scotland and the Commercial Bank of Scotland — two institutions that had operated independently since 1825 and 1810 respectively. By 1967 the bank was already in merger talks with the Royal Bank of Scotland, a union that was completed in 1969, making late-date issues like this one short-lived survivors of a rapidly consolidating Scottish banking sector.

The £100 denomination saw almost no retail circulation by the 1960s; notes at this value moved primarily between businesses and banks. De La Rue had printed for the National Commercial series throughout the bank's brief existence.
