I once tried to collect hockey trading cards, along with other sports, and kept them as a hobby through most of my formative years. I tried building a whole set of1993-94 Leaf once by purchasing the common cards at 5 or 10 cards at a time. So, I know a little thing or two about the trading card industry.
Imagine the smirk on my face that must have happened when I spotted the headline hyperlink reading about a recent auction for a Wayne Gretzky rookie card. Someone with either a lot of cash or a lot less brains had spent $94,163 on a mint grade rookie card made in 1979 by O-Pee-Chee. It was done at an auction in California.
What I learned about the competitive nature of the trading card industry is that the value of cards go up and down just like Wall St. stocks and ultimately a slave to the value the market assigns it. Buy low and sell high. Unless this person wants to keep the card for life, I don't see them getting any value back from another buyer willing to spend more on the card than they have already.
