Estimation Contest: Guess the Total, Win a Book

This wooden box sits on top of my dresser, and every afternoon when I come home, I dump the change from my pockets into it. It’s getting close to full, as you can see:

I’ve got a couple of extra galley proofs kicking around, so here’s a contest:

Guess the total dollar value of the change in this box.

Leave your guess in the comments. I will take the box to the bank next Monday, and have the change converted to folding money. At that time, the commenter whose guess is the closest to the actual dollar value of the change in the box (above or below) will receive a galley proof copy of How to Teach Physics to Your Dog (I’ll announce the winner Monday afternoon, and will contact the winner to get a mailing address).

All coins in the box are US currency. (Well, ok, I see a chip of ceramic from something else in the picture, but everything else in the box is US coinage…). Guesses should be presented as a decimal number, to the nearest cent. In the unlikely event of a tie, I will choose a winner, or let SteelyKid pick.

One guess per comment, please.
