="Yancy Street Gang"]I remember knowing somebody who was hoarding Gregg Jefferies rookie cards, figuring to one day cash them in to pay for his kid's college tuition. I said, "Don't you realize that there are many people doing this? And because of supply and demand, those cards are going to be virtually worthless, even if Jefferies becomes the next Ty Cobb?" Deaf ears. If Mickey Mantle is worth thousands, then so must Jefferies. When I was very young, I thought that each of my comic books would become very valuable thirty years later, since Golden Age comics were selling for so much. I wasn't much past my tenth birthday when I realized that the supply of Marvel Two-In-One would always be high, but the demand would always be low. Supply and demand is a worthwhile thing for people to understand. And it's not even a difficult concept. Heh, good point, look at that Piazza card I posted some time ago. Considering Mikey's place in history, regardless of the fact that Carlos Delgado is putting up "HOF consideration" numbers as well, Piazza's Topps rookie card should be right around what Johnny Bench's card currently goes for. But because of the same market winds that hurt the Jefferies market makes that card available for less than a buck these days. For a guy who is easily top 5 all time catchers in MLB history (Bench, Berra, Cochrane is up there, peeps will put Gibson on that list, see how the steroid era shakes out to put Pudge Rodriguez on the list) and a very popular player in both largest markets in the country, (LA and NY) not to mention playing on the second most popular team in the sport's history (Dodgers behind the Yankees), that truely is a pathetic sign of how speculation destroyed the hobby
