The Vibram collector's spend a lot of dough on rare items, which may/may not impact the performance.
An example from my experience: I own three pre-PDGA putters, and I've found them to be excellent performance-wise, so I've kept them over the years. Granted, they're only worth a few extra bucks on the market, but I've found them to be excellent quality.
Another example: proto-discs will sell for 2X or 3X as much as they purchased for, simply because they are rare items.
