Pricing

There are probably a hundered different factors to take into account.
Home casting or casting company? What country does the artist live in and how much tax do they have to pay? What about living costs there, what do the artist need to live? Experience level of the artist? Hobby or professional?
And then there is the doll itself. Size? Weight? Complexity?
I think asking for an average is kind of the wrong question. I have seen artist dolls in that general size range go for anything from bare material cost up to thousands of dollars, but since those dolls have not been comparable, it doesn't mean much.
Add to that the fact that many well known doll makers are technically independent doll artists, doing all or most of the work on their own. You can just look around and collect the prizes yourself from whatever dolls you feel are relevant to you and calculate the average.

 

Yea... If the real question is how you should prize your own doll... Well, that's a very different qestion and one probably impossible to answer before you have goten your hands dirty and gone at least some way into the process.

I will give this advice though: Don't sell yourself short!
If you truly want to make a living making dolls you have to approach it from a business centered mindset. You may have to make decisions based on cost rather than artistic integrity, especcially in the beginning. One of the most common runaway costs in first dolls is falling for the temptation to add too many parts, forgetting that every part may add about equally to the prize of the finished product. Double joints everywhere? Well, that may take the body from 14 to 18 parts. That's quite an increase and will the additional parts actually bring enough value to the finishe product to justify the increase in prize? Same thing about extra posed hands, heeled feet optional sleeping head etc. It's easy to almost by accident suddenly have a product that will cost twize as much to produce. And if it's all offered as options, then there will be a lot of extra handeling and planning when it comes time to actual production and that has to be reflected in the prize if you want to make any sort of a profit.
So if you know going in that you want to make a comersially viable product, shape the entire process with that in mind.
Start simple, get the process down and then you can start adding extras. Remember that once the doll is in a casting ready stage, you can keep selling that same doll over and over. That is where the profit lies.
