Off from Veggies for a Second

Trying my hand at profundity:

Suppose you have a painting in your attic that was given to you years before.  At the time the painting was given to you, you were told that the painting was done by a hobbyist, and is essentially worthless.

You decide to donate the painting to your church for a garage-sale fundraiser, and in the course of making the donation, you learn that the painting is not worthless, but is actually worth $100,000.

Do you still donate the painting?  If you do, you are in the situation that you had planned to be in before, meaning you no longer have the painting.

I suppose most people, including myself, would not donate the painting, as our heads would be filled with thoughts of the great things that could be done with the $100,000 (which would all probably focus on the accumulation of material things).  And what motive would I have for keeping the $100K?  I am afraid that it would be deep dark greed.
