The egg is one of a series of 19 fashioned by the goldsmiths in 2005 to represent the number of medals won by Jimmy "Jinky" Johnstone.
Johnstone was voted the greatest Celtic player of all time by fans of the club and is said to be one of the greatest ever Scottish footballers.
He died in 2006 after a long battle with motor neurone disease.
The egg, number 18 in the series, opens to reveal a silver and gold figure of the player. The last example to be auctioned fetched £14,600 several years ago.
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 it is believed a number are owned by leading figures in football."
