That depends on the cost of the supply. Buy cheap supplies you get dolls like the one I have with lumpy paint. And Paint in general is not very cheap.
And depending on the size I can forsee 50 for a stuffed and 100 for a baby blanket, depending on the size of the bracelet and if you can find chainmail fanatics would be if you could sell that for 60.
The biggest thing is not selling yourself short as an artist. I see this happen often also with my friend who does hobby professional cake baking, where people expect things super cheap because it's a one time use item. But it takes her at least 2-4 hours to bake the cake, then up to 6 hours decorating with fine details and even spray painting details on late at night, so of course shes gonna charge 200 for a 2 tier 25 person cake.
Artist often sell themselves short just to get their product out -enter starving artist joke- so when it comes to making sure you get paid for your work, people trying to make a living off this will be charging what they feel they are worth.
It took me 5 days in between real life and work to make that one doll. Even if someone was just sitting there doing it for hours, they have to let the paint dry and spray a set before they can continue on the next layer.

Another thing is marketing. The OOAK Doll collectors are also the kind of people spending hundreds on other kinds of dolls too (Like porcelain or resin ball-jointed) So considering that 150 would be a regularly priced doll.
