The infamous mouthguard that first made headlines early in the Rugby World Cup was last night set to fetch up to $10,000 - the same amount its user was fined for wearing it.
Samoa winger Alesana Tuilagi broke International Rugby Board rules and was fined for wearing the unauthorised OPRO mouthguard.
Days later, younger brother Manu Tuilagi, 20, an England player, was fined the same amount for wearing a similar shield.
Alesana Tuilagi has since offered his mouthguard, autographed, for auction on Trade Me.
He has also included the boots he wore during Manu Samoa's 13-5 defeat to reigning Rugby World Cup champions South Africa.
