Proof banknotes are a specialised form of currency produced during the design and production process to demonstrate the intended final appearance of a banknote. These notes are carefully created to showcase the intricate details of the design, including the artwork, security features, and overall aesthetics.
They are often used for approval purposes by central banks, currency printers, or designers before the final production of a banknote.
Collectors also value proof banknotes due to their rarity, and the insights they provide into the banknote design and production process.
