The value of old Ping putters is determined by researching golf club appraisal websites. Such websites feature search bars that allow users to narrow their inquiries by brand, age and club type.
Putters are by far the most unique golf club available; golfers are notoriously finicky about their short game, and putter values are prone to fluctuate because of this. Overall popularity, design trends, personal taste and celebrity endorsements all factor into a putter's worth. Ping is a nationally-recognized brand, and Ping putters tend to hold their value better than other clubs.
It is wise to consult with a golf club appraisal website when looking to purchase or sell old clubs of any kind. Taking clubs to a qualified dealer such as Golfsmith or Golf Galaxy is another good way to get a quick appraisal. In many cases, retailers offer trade-in values on the spot. Since putters are often purchased separately from woods and irons, it is possible to buy and sell these clubs individually at stores and pro shops. Condition of a putter's club face, shaft and grip are important when considering a trade. If a putter is deeply scarred or the shaft is bent it diminishes the value significantly.
