$400 may have been the actual high price, but if someone had purchased one share in '97 for $10, when it was $400 share, that person would have $1600 worth of Apple stock. This is due to the fact that the stock has split twice since he came back in the mid '90s: http://investor.apple.com/faq.cfm?FaqSetID=2
I had $10 back then, too, even though I was about 9. I remember thinking "the stock market seems interesting"... It's just cool to think that my $10 could've turned into $1600 with nothing but luck and patience.
