Hi Phyllis,
Sorry for the delay, I've been working full time again and we moved, so I've been away from the forums.
From what I saw on Ebay, there is not much of a market for them. Apparently, if you have a particular "princess Diana bear" it's worth money, but that doesn't mean anyone is buying them right now. If you love them, I would just keep and enjoy them and not worry about what they might sell for.
