So, How much is the full 11x17" Educational Think Different Poster Set Worth?

[mgartner0622]

I have a set of 10 Apple Educational Posters. They are in mint condition, apart from two pinholes in each poster. They are all 11x17. How much are these actually worth? If they are worth quite a bit I'm thinking of selling them then donating the money back to the school I got them from.
Thanks!

Also, I was looking at images online. The posters I have feature a white apple logo. Not the older "vintage" colored one.

EDIT- It is the 11x17 ones on this page.

Seem to go for $100+ on the 'bay. Best way to find out is to list them.
