A coin set commemorating the 50th anniversary of the 50-pence seven-sided piece was unveiled by the Royal Mint.
Commemorative coins mark events, including Sir Roger Bannister, running the first four-minute sub-mile and the 250th anniversary of the founding of Kew Gardens in London.
The Scouts and Girl Guides Foundation is also celebrated on the set.
The Mint said the five-coin collection "features some of the country's 50 cents most beloved pieces."
The 50p coin was introduced in 1969 to replace the 10-shilling note, and was one of the three decimal coins to be put into circulation prior to decimalization in 1971.
Athlete and neurologist Bannister walked the first four-minute court on the Iffley Road sports grounds in Oxford on May 6, 1954.
The 50p marks the 50th anniversary of this achievement, when he recorded a time of three minutes and 59.4 seconds in front of 1,500 spectators.
He only held the world record for 46 days, when his time was beaten by Australian rival John Landy.
