Time will tell when such "insanity" will prove to have shown such brilliance and excellent foresight. I think we were saying the same thing when a fuzzysloth hit the scene a while back. That guy did all right I believe!
All in all, how cool is it that there are people out there that have items in their collection that even the Hall of Fame wished they had!
I don't think it was too much. In the late 1990s I passed on a $1200 Lou Gehrig Zipperback and a $400 webless workmans. The Dow at that time was not much different than now. Great and rare collectibles, whatever the category, are worth it (as long as you have money!)
