10 Dollars - Elizabeth II Posthumous, Great Train Robbery

The Great Train Robbery of August 1963 netted the gang approximately £2.6 million — equivalent to roughly £55 million today — making it one of the largest cash thefts in British history at the time. The operation's meticulous planning, involving a rigged trackside signal near Bridego Bridge in Buckinghamshire, briefly elevated figures like Ronnie Biggs to a strange folkloric celebrity, particularly after his 1965 prison escape and decades-long flight to Brazil.

Solomon Islands has issued this piece under a posthumous Elizabeth II obverse, a minting convention adopted by several Commonwealth and associated issuers following the Queen's death in September 2022 to exhaust contracted design programs.
