1 Guinea = 1 Pound 1 Shilling Sterling

The guinea denomination — one pound one shilling — was an unusual choice for a banknote, rooted in the practical reality of Scottish commercial life in the mid-eighteenth century. Guineas were the standard unit for professional fees, land transactions, and gentlemen's accounts, so a note denominated in guineas allowed merchants and lawyers to settle debts without calculating conversion. The Royal Bank had been issuing notes since 1727, and by the 1750s was already well established in Edinburgh's financial community.

Hand-laid paper of this period was sourced from Scottish mills and carries the characteristic chain-line pattern visible under raking light. Notes from this series are exceptionally rare in any condition — most that survived did so in institutional archives rather than through normal wear.
