5 Soles

The Banco de Londres México y Sud América was a British-chartered institution operating in Peru, and this 1866 issue predates the establishment of a Peruvian central bank by decades. The American Bank Note Company held a near-monopoly on South American commercial bank printing at this period, supplying plates to dozens of competing institutions across the continent — which is why notes from entirely unrelated banks of this era can look strikingly similar in their engraving style and border work.

The "Soles" denomination reflects Peru's 1863 monetary reform, which replaced the old peso system. This note is among the earliest issues under that framework.
