The "auction" (for lack of a better word) is over. Look at what happened.

One could just as easily say a Warhol is merely some canvas and paint. It's all so subjective. I personally don't believe in comparing one realm of collectible to another. Some cards were mass produced, others are in incredibly low supply relative to demand. One cannot underestimate people's love of sport, sports icons, and all the nostalgia as well.

Art being considered "higher" troubles me. To be clear, not saying you are saying that. But for those who would, it's kind of a pretentious, condescending attitude. There is room in a society for for both fine art and for sport. And one could contend sport is far more popular than art in society. I'm not someone who's big into prognostications but I don't see high end art or high end baseball cards becoming worthless in my lifetime.
