100 Pounds National Bank of Scotland

The National Bank of Scotland merged with the Commercial Bank of Scotland in 1959 to form the National Commercial Bank of Scotland, making 1957 issues among the final notes produced under this name. Waterlow & Sons had printed for the National Bank across multiple high-denomination series, and by this point the relationship was nearing its end — Waterlow's banknote division was absorbed by De La Rue in 1961.

At £100, this note would have seen almost no retail circulation. High-denomination Scottish notes of this period moved primarily between banks and commercial houses, and surviving examples tend to show relatively little wear for that reason.
