Prince Charles' 70th birthday is to be commemorated with a special £5 coin.
An engraved portrait of the Prince of Wales, who turns 70 on November 14, will feature on a series of souvenir £5 coins, with his mother, Queen Elizabeth II, featuring on the reverse side of the coin.
The £5 coin can be purchased from the Royal Mint with prices ranging from £13 for a brilliant uncirculated coin to £4,000 for a platinum version of the piece.
The 69-year-old is already immortalised on coins which celebrated his 50th and 60th birthdays.
Here's how much the coin could be worth in the not-so-distant future, judging by the prices of previous commemorative coins
