1. Muhammad Ali 2010 Leaf Base Card #100
Comments: Originally thought to be “just another base card,” it has been realized that this card is SSP’d. For those of you still interpreting the card acronyms, that’s Super Short Printed. At one point in time, this card was available for a couple bucks like any other base card, now its available for $100-$200 bucks. That’s a whole lot less available and a whole lot more hot.
