The value of rare golf clubs are listed in the 1997 book "Antique Golf Collectibles, A Price and Reference Guide" by Chuck Furjanic. Rare clubs that show little use bring higher prices. Rare golf clubs include irons that have unusual head shapes or face markings, or that lack face markings.
Other rare golf clubs include putters with wood heads or unusually shaped heads, and woods that have a thick, curved, oval neck with a four- to five-inch covering of string whipping. Irons with smooth faces bearing the names of Army & Navy, Anderson, Ayres, Carrick or Forgan are uncommon. Smooth-faced irons with the names Park, Gray, Morris, and White are also collectible. In some instances, irons with smooth faces by MacGregor, Condie, Spalding, NicoIl, Gibson, Stewart, and Wright & Ditson may be considered rare clubs.
