10 Pounds
The States of Guernsey introduced an updated 10 Pounds banknote on January 19, 2023 as part of the comprehensive security modernization of all Guernsey pound denominations. The note features Queen Elizabeth II on the obverse with Guernsey's distinctive design elements, maintaining visual continuity with earlier issues while incorporating significantly advanced security technology produced by De La Rue.
The primary security advancement for this denomination is the introduction of the IGNITE windowed security thread, which shifts dynamically from blue to green with a pulsing pattern that shows visible movement effects when the note is tilted in any direction. This represents a significant upgrade from previous security thread technology and provides an easily verifiable authentication feature for everyday users. The IGNITE thread technology is part of De La Rue's portfolio of advanced optical security features designed to stay ahead of counterfeiting methods.
Guernsey's 10 Pounds denomination plays an important role in the island's everyday commerce, and the security upgrade was timed to coincide with updates to the 5 and 20 Pounds denominations for a coherent modernization of the complete banknote family. The States of Guernsey's decision to maintain Queen Elizabeth II's portrait on the updated notes reflected established practice of issuing currency during production cycles rather than transitioning immediately to a new monarch's portrait.
