My daughter has been collecting them since 2006 has a few foils and wants to sell them all now to save up for a computer lol. Oh well I buy them for her and she wants to sell them and keep the money. I can shoot you a list of what she has if you are interested.
My son plays with them. I'm sure he would love anything I could get for him. I have no idea what anything is worth, so I am not willing to pay really much, if you are trying to get rid of some, I know a 3-year-old who would love to play with them.
