100 Kolonata - Zakynthos

The Ionian Bank was chartered by British act of parliament in 1839 specifically to serve the Ionian Islands, then a British protectorate. It held a note-issuing monopoly in the islands — an unusual arrangement that gave a privately incorporated London bank full currency authority over a nominally self-governing Greek-speaking territory. This note was issued for Zakynthos, one of several branch-specific issues the bank circulated across the island group, each payable at its respective island office rather than through a central clearing point.

The kolonata was the local unit, pegged to the Spanish dollar. Surviving examples from the 1843–44 period are rare; the bank's early issues had low print runs and the islands were never a high-volume commercial environment.
