Honest Abe wrote to a group of schoolchildren asking him to "free the poor slavechildren," and told them of how moved he was to get their letter.

That letter will be on the block in early April at Sotheby's, and could well bring $5M.

It's hard to say which I would rather have; this, or the Triceratops that Christie's will auction off in three weeks.

On one hand, you have a letter from Abraham Lincoln addressing the seminal issue of emancipation - a decision on his part that has effect even today, and on the other you have a Triceratops...

I'd have to go with the dinosaur. Does that make me a bad person?
