I don't, and it seems the older board members no longer stop by here. Most everyone would say to research the dolls on eBay (the sold lists, to see what prices things brought) and sell them there. It can be a process.
If you have older dolls (originals or Mod era) or something really collectible, you could see if somewhere like Joe's List or MarlB would be interested. Or try an auction house, though I have no idea how to go about finding one.
Sadly, I don't thing there's much money to be had in common play dolls, or even some of the ones that people used to be crazy about, like the Holiday issues, but I'm not an expert by any means so it's best to do your research and see what things have sold for previously.
