Our family has this tradition, from where it started I have no idea, of putting coins in the easter eggs. It was always fun as a kid to try to find the most money. And we have continued it with our kids too.
One day, after the easter festivities had ended, I took the girls money and put into bowls for each of them. They brought out their piggy banks and sat at the table putting their coins, one by one, into their banks. It was fun to watch them.
