Where can i sell my 2 Ashton Drake dolls?

I have 2 Ashton Drake Galleries porcelain dolls from 1995, My Little Ballerina and Sunshine & Lollipops, in their boxes, in excellent condition and with their certificates of authenticity. I have posted them on ebay but to no avail. Does anybody know where else i can sell these? I also have 2 Leonardo Collection dolls.
