Scottish banknotes are not withdrawn in the same manner as Bank of England notes, and therefore several different versions of the Clydesdale ten pound note may be encountered. The "Famous Scots" issue of the £10 note featuring missionary Mary Slessor was introduced in 1997. On the reverse of this note are a series of images connected to Slessor's work, including a map of the area in which she worked and a vignette showing her work with children. In 2006 a version of the Slessor note marking the bank's sponsorship of Scotland's Commonwealth Games team was produced. This note has an alternate reverse displaying a montage of sporting events. The "World Heritage" series £10 note was introduced in 2009. This note featured a portrait of Scottish poet Robert Burns on the front, and the Old Town and New Town of Edinburgh on the back. A new polymer note went into circulation in 2017, replacing previous cotton issues. This new note continued to feature Robert Burns on the front and views of Edinburgh, including Edinburgh Castle, on the back. The Committee of Scottish Bankers encouraged the public to spend or exchange older, non-polymer ten pound notes before 1 March 2018.
