I've got a £50 Turing banknote!
I have written before about my interest in Turing.
In 2018, the Bank of England decided they wanted a scientist on the new £50 note and invited nominations from the public. In six weeks, they received 227,299 nominations with 989 eligible names. With the help of public focus groups, their advisory committee determined a final shortlist of one dozen. The bank's governor, who makes the final selection, announced the choice of Turing in July 2019. The design was released in March 2021, and the bills were issued June 23rd.
Although the US Mint sells coins and bills direct to the public, the Bank of England does not. After declaring everywhere that I wanted one, a computer science teacher friend said she wanted one, too, and she asked another math teacher friend with family in England, and that connection worked.
