They remind me alot of the porcelain dolls that my grandmother used to collect, too. I'm afraid that I can't help you one bit with values, especially not with ones that are smokey; that's a right shame since that will turn off a fair few collectors.
My experiences with trying to sell porcelain dolls for anything close to true value/ original sticker price has always been bad. I don't know if they don't hold their value or if people just don't collect them anymore, but I've never had good luck trying to sell them. Which is why I have a few in my own collection!
Maybe someone more knowledgeable will show up. GL with them, whatever you decide to do with them!!! They are very pretty little dolls!!
