100 Pounds Commercial Bank of Scotland

The Commercial Bank of Scotland was established in Edinburgh in 1810 as a deliberate challenge to the near-monopoly grip of the Bank of Scotland and the Royal Bank — it was explicitly founded to serve the merchant and trading classes who felt locked out of established banking relationships. By the time this £100 series entered circulation, the bank had grown into one of Scotland's principal joint-stock institutions, with a branch network extending well beyond Edinburgh.

Bradbury Wilkinson printed extensively for Scottish private banks during this period, their New Malden works supplying notes across multiple issuers simultaneously. The Commercial Bank would ultimately merge with the National Bank of Scotland in 1959 to form the National Commercial Bank of Scotland.

A £100 denomination in this era was almost exclusively a commercial instrument — inter-firm settlements, property transactions, rarely if ever passing through ordinary retail hands.
