Omg.......10 Euro for a tooth, you are definitely spoiling it all for the rest of us. :p And it does set a precedence for future Fairy payments. Like you said, it will never go down, ever!

We keep the 1 & 2 dollar coins and try to polish it up a little to make it look nicer. Also, the tooth fairy also leaves a little note to encourage her to do things her parents would like done :D
