The egg, which went under the hammer in Glasgow, is one of a series of 19 items fashioned by goldsmiths in 2005 to represent the number of medals won by Johnstone, voted the greatest Celtic player of all time by fans of the club. The keepsake opens to reveal a silver and gold figure of the player.
Brian Clements, managing director at McTear's Auctioneers in Glasgow, said: "Not only are the Jimmy Johnstone Faberge eggs remarkable examples of high-quality jewellery in their own right, they are also important pieces of football memorabilia. The eggs are highly sought after by collectors and there was a lot of interest in this particular egg."
Johnstone was 61 when he died in 2006 after a battle with motor neurone disease.
