'Tiger Slam' clubs are up for sale again -- and could sell for more than a million dollars

Tiger Woods waves as Vijay Singh looks on during the presentation ceremony of the 2001 Masters tournament.

(CNN)For those looking for a piece of golfing history -- and with a seven figure sum to spare -- the clubs that Tiger Woods used to win the "Tiger Slam" are up for sale for the first time in more than a decade.

After a grueling four days at Augusta National in 2001, Woods sunk a two-putt to win his second Masters and become the first golfer to hold all four major titles at the same time. He had won the final three majors of 2000 - the US Open, The Open and PGA Championship -- before securing victory in Augusta.
And the irons and wedges Woods used in 2000 and 2001 as part of his historic feat are now up for auction.
    The clubs -- 2-PW Titleist Forged irons and two custom Vokey wedges, both stamped "TIGER" -- were last privately auctioned in 2010, and had been displayed privately in a Houston office complex, according to US based auctioneers Golden Age Golf Auctions.
      The custom Vokey wedges are stamped "Tiger."
      The wear mark on the face of the 8 iron has been described as "otherwordly," while the 58 degree wedge is bent to 56 degrees.
      As you might expect from such record-breaking clubs, the items are well used, according to auctioneers, who say a wear mark on the face of the 8 iron is "otherwordly."
        Meanwhile, the 58 degree wedge is bent to 56 degrees and hand stamped "56*".
        Auctioneers say that the clubs should sell for seven figures.
          "I do wonder if [the irons] will be the first golf collectible to break the $1 million mark," Golden Age auctioneers founder Ryan Carey told Golf Digest.
          "It's not like there are many people collecting used iron sets, as it's just not feasible, so it's hard to know the market. These aren't exactly baseball cards."
          "The Tiger Slam irons come with a substantial amount of provenance, including affidavits/declarations of the two Titleist executives both in charge of Tiger's clubs and witness to the exchange when Tiger gave the clubs away," the auctioneers said on its website.
            Golden Age Golf Auctions also said that former Titleist Vice President Steve Mata had passed a polygraph test in 2010 regarding the validity of the clubs.
            "We also have a copy of a September 2000 Golfweek magazine article that detailed the exact specs of Tiger's clubs used to win the 2000 PGA Championship, and they match the offered Tiger Slam clubs perfectly, including the 58 degree wedge bent to 56 degrees," they added.
