JimCrandellPSA 8 or 9 T206 commons are a great investment--you just have to pick your entry points. I have 125 or so psa 8 commons with an average cost of $300-$400. I think scarce cards in poor-fair-good condition will be poor investments. Investors generally want top condition cards.
I also disagree with the notion that if a few more of a card are graded it means the price will go down. Its supply and demand and if the supply goes from 20 to 25 of a mantle in psa 9 over three years but the net demand grows at 10% per year the price goes up.
