clowns to be auctioned

My mother collected clowns and has 11 Porcelanas Casades clowns, several flat-bodied clowns made in Cabrelli, Italy, half a dozen Emmett Kelly clowns, and many small pewter clowns. As she is now residing in a nursing home, we will have an auction of her household belongings on Saturday, October 6, 2007, at her home in Grain Valley, MO by Keim Auction Service. I would like any response from anyone with info on possible values of the clowns. The Porcelanas Casades clowns were puchased by my mother at auction several years ago and she paid slightly over $100 per clown at that time. She has one Lladro figurine, but it is not a clown, and I have found a list value for that figurine at $325.
