20 Pounds

Cyprus joined the eurozone on 1 January 2008, at which point the pound was superseded at a fixed rate of 0.585274 CYP to one euro — a rate set with unusual precision to minimize rounding losses on conversion. This final series of pounds, of which P#63 is the highest denomination, had a relatively short active life as a result, with redemption of unexchanged notes continuing through the Central Bank for years afterward.

Thomas De La Rue's involvement here is unsurprising; they held the Cyprus contract through most of the post-independence period. The holographic strip was a late addition to the security specification, introduced in response to regional counterfeiting pressure during the late 1990s.
