What is the most expensive 80s card out there?

[FLOUR]

This doesn't include minor league cards, graded cards, or cards numbered to 25 or less.

I'm more curious to find out if there are any 80's cards serially numbered to 25 or less. My 80's knowledge spans overproduced base cards but that's about it. Can anyone think of any?

To my knowledge, serial numbering didn't exist (in anything mainstream) in the 80's.

I thought the '91 Donruss Elite were the first numbered cards in baseball.
