Why does anyone collect anything? Putters, Cars, Thimbles, Old Radio's!?! To each their own. However, I'd have to speculate that a lot of golfers or proclaimed "Putter Collector's" collection usually begin because of their tireless search for their "magic" stick and they simply start stacking up in the garage. Case in point.....I have a buddy who is a very good single digit golfer. However, he's always tinkering with putters.....I wouldn't be shocked if he has over 12 expensive putters of different shapes and brands.
For me, I've dabbled in collecting SC putters and accessories. I do it because I like it and I absolutely love the game of golf. A lot of guys have sports memorabilia in the "man" caves or offices.....why not golf related?
I don't collect run of the mill putters.....but, I own, or have owned multiple Circle T, limited release putters (My girls). If you know the market, know what you are doing, you can actually make a few bucks here or there or at worst break even buying and selling SC putters. I purchased a SC CT 009 putter in 2008 for $1900. Gamed it up until a few years ago and sold it last year for $2500. Not a bad ROI for a used putter. My current gamer is a CT X5 that I'm confident will make a few bucks if I ever decide to sell it. Right now, it's NOT going anywhere. As, putting is one of my strong suits in the game and I absolutely love it!
