10 Pesos

The Falkland Islands pesos notes of the 1820s were issued under the short-lived Argentine presence on the islands — specifically tied to the settlement established by Luis Vernet, who received a land grant from Buenos Aires in 1823 and was attempting to build a functioning colony. The denomination itself reflects the Argentine monetary system then nominally in force, not any British one.

Britain reasserted control in 1833, rendering these notes obsolete almost immediately. Surviving examples are exceptionally rare, and the Pick S104 designation places it firmly in the speculative/local issue category — documentation on actual circulation is thin at best.
