I've found that the higher graded older stuff has increased in value quite a bit. I think for a lot of people, they collect cards as kids, then stop, and eventually start again when they're older and can afford the cards they couldn't when they were a kid. At least, that's where I'm at. I've been putting together a PC of Boston rookie cards and old HOF's. Some of my favorite cards are guys from the 70's and 80's that I can remember watching and hearing about from my older brothers. It's still funny to me that 80's are considered vintage now =).
