1 Pound Asiatic Banking Corporation

The Asiatic Banking Corporation was a British overseas bank incorporated in 1863 with ambitions to compete in the China and India trade corridors, but it collapsed in 1866 — one of several casualties of the Overend, Gurney & Co. crisis that triggered a severe London banking panic that May. Notes from this issuer almost certainly had negligible circulation before the bank went under, meaning surviving examples were likely never spent.

Smith, Elder & Co. are better remembered as publishers — Thackeray, Charlotte Brontë — than as banknote printers, which makes their involvement here an oddity worth noting.
