Comics from the last 30 years worth more than $300

Bleedingcool.com says there are only 10 comics from the last 30 years that are worth more than $300, assuming they’re in really nice shape. I have one of these that I bought new, but my copy is damaged (stupidly by me when no one knew it would be worth anything.) which cuts its value in half or more. I’m pretty sure I had another, but traded it away years ago for some books that were by far better cartoonists than Rob Liefeld.
