Dolls?

Does anyone know anything about collecting/appraising antique dolls? I have four that I dug up in my basement a little while ago, and while I know what they look like and their creators, I have no idea whether they are valuable or not. I have done a little research so that I can accurately describe them, so if you know anything about dolls I would appreciate an assist!

I have looked on Amazon, Ebay, and Google Shopping for the specific dolls and haven't come up with anything even similar to them. When I look at their brands and collections I get an idea of what they should be priced at ($15-$40 depending on the dolls), but if they are particularly rare or valuable I would appreciate getting my money's worth.

Doll #1
This doll is a Seymour Mann Connoisseur collection Limited Edition of 2,500 pieces with a "Certificate of Authenticity" signed by Seymour Mann. The back of the neck has a trademark for Seymour Mann and the Connoisseur collection on it as well as the doll's number, MCMXCI. She appears to have a head and all 4 limbs made of celluloid with a cloth body. Blonde with straight forehead bangs and blue eyes with eyelashes, wearing a blue flower-print dress with a bib, basket of flowers, and straw hat with a matching ribbon. She is fully clothed with all her original pieces, but her hair has been unbraided. No box.

Doll #2
Unmarked on the back of neck and otherwise unbranded. Tag on her body says she was made in China. This doll also appears to be made of celluloid, again with a cloth body and hard head and limbs. She has greyish-blue glass eyes with eyelashes, blonde hair elaborately styled with many curls and a scarlet bow, and an ankle-length dress with a maroon velvet bodice, beaded white lace bib, and satin/chiffon skirt with beaded bows. She comes with a small hand purse, also made of satin/silk and attached to the skirt of the dress. Her left arm is shattered, but still attached to her body.

Doll #3
Also a Seymour Mann Connoisseur collection doll (this one may be the part of the Limited Edition series with the "Certificate of Authenticity"). The back of the neck is marked as Seymour Mann and part of the Connoisseur collection. There is no number for this doll. She has a cloth torso, but celluloid arms, legs, and head. Her dress is mid-calf, made of black velvet with a black satin lining and white lace neckline and sleeve ends. The bodice was once beaded with four strands of pearl-like beads; only two columns of beads are left. Bright blue eyes with eyelashes and blonde hair styled elaborately with many curls and a faux-flower decoration. Victorian(?) style. The crown of her head has been smashed and she rattles when shaken, but no pieces have fallen out.

Doll #4
A Heritage Mint Ltd. doll (1988-1989). Brand name and dates marked on the back of the neck. No number for the doll. Cloth torso, but head, arms, and legs may be bisque. Carrot-red hair with straight forehead bangs, styled into a curly ponytail. This doll was purchased from someone else, so this may not be her original hair style. Brown eyes and painted-on lashes. More petite than the other three dolls. Her outfit consists of a white bell-sleeve, turtleneck under dress; a red bodice laced with thick gold thread and pearl-like beads; a red, white-lace-hemmed overskirt made of the same material as the bodice; a white apron lined with the same lace as the red overskirt; a pair of white stockings; and detailed white lace socks. She also has a detachable straw hat with the white lace from the rest of the doll and a thin pink ribbon. No damage, but the left shoe is missing.

So, if you could help me, that would be wonderful! I'm looking to get these sold as soon as possible, as I'm leaving for school and need the money and space. Feel free to leave a comment or note me privately if you are interested in purchasing them yourself or need more details on a particular doll!
