Putting a new meaning into "don't spend it all in one place".

Kids, gotta love that they have no logic whatsoever. Don't give paper money to kids, people.

Kids just don't give a shit

No problem. Just take the bill out and change it into a new one at the nearest bank. As long as you have most of the parts they will do that without questions. You can also let it stay inside the piggy bank until needed.

Why would a bank give you a new one for a ruined one?

You have to have 50% of the bill at least intact. They will not do it if it is torn into shreds.

Midnalink, I couldn't reply to you so I hope you see this. Most countries use banks as a means to filter damaged or older paper bills out of circulation. The banks introduce newly minted money and remove the old on a regular basis, and will often accept damaged bills in exchange for a deposit or new bill. That or call your country's treasury and they will do the same.

Paper money doesn't belong in a piggy bank to begin with. As a kid, I had a pencil shaped one, and a Hershey plastic cup for my paper money.

Your son is a genius! He just increased the value tenfold. A bunch of 20 euro bills is worth more than one.

Tape it back together. And keep on trucking.

it's disconcerting that nobody knows enough about money that everyone thinks that the bill has somehow lost its value. including the editors.

Why didn't you help your son to carefully fold it and put it in?

I will never understand why the majority of the world doesn't use plastic notes :S we do in Australia and never have this problem, or a problem w leaving money in pockets in the wash...
