I'm thinking about selling a few modern high value cards and re-investing that money into vintage. My thought is I'd like to keep the money in my collection, but thinking vintage is a safer bet to maintain value over the long haul. For the sake of argument, lets say the value of the vintage card is around 2K somewhere. Something like a '55 Clemente PSA 6, or '33 Goudey Ruth PSA 3.5...something like that, that will by far be your best card both in wow factor and price.
My thought is these types of cards don't really go down in value, only up. The player can't go on a hot streak, can't win an award, can't get elected to HOF again, and more than likely cant die again. Those of course being the main milestones where a current players stuff would go up/down throughout the course of his career. I don't follow the price path of these types of cards on a close enough basis, so was curious of everyone's opinion on going this route.
I guess this could also lead to the question of where you think the card market is going to be in 10/20/30+ years from now. (which I know has been talked about on here before)
