When the Barbie doll debuted in 1959, she flew off the shelves at $3 a pop. Today, though the price of some new Barbies can start as low as $10, the value of certain older models has skyrocketed over the years. Obviously, an original Barbie Millicent Roberts doll (yes, she has a full name!) in her black and white striped swimsuit will cost a pretty penny; this blonde version is currently on Etsy for $5800, while another is on sale at Ruby Lane for $4495. But even some that you may have played with as a child—like this $148 Talking Teacher Barbie from 1995 who is dressed like a glamorous Ms. Frizzle—will set you back quite a bit if you want to recreate your original collection. Check out these seven other surprisingly expensive Barbies that you can buy right now.

1. TOTALLY HAIR BARBIE

First released in 1992, Totally Hair Barbie had a mane of completely unreasonable Rapunzel-esque hair that went all the way to her toes. With more than 10 million sold, Totally Hair is the best-selling Barbie ever. But even with so many originals out there and a 25th anniversary doll that also sold well, there are plenty of boxed '90s dolls on eBay—both blonde and brunette—going for more than $50. Who knows if that Dep hair gel is still any good, though.

2. VINTAGE BENDABLE BARBIES

Barbie's stick-straight posture got a little more human when "bendable" versions began coming out in the '60s. Sure, it was just her knees that bent, but that little movement made her look much more convincing while "walking," like this Skipper doll who is ready to romp on the beach with her new-found mobility. (Now, of course, some Barbies are bendable enough to do yoga). Buying an early model of this new design can knock you off your feet though. This used, 1965 bobbed-hair American Girl Barbie with only one leg that still bends properly has set the opening bid at $400 (which seems like a lot, until you see the same doll in new condition asking for more than $3000).

3. CHRISTIE DOLLS

The first Christie doll was a 1968 talking version, and since then, the African-American doll has been a consistent member of the Barbie family. Nice, boxed Christies can command several hundred dollars, like a 1976 SuperStar Christie asking $875 or this 1981 Golden Dream Christie priced at $300, but even a $100 Kissing Christie is a steep price compared to what she would have retailed for in 1980.

Pro tip: The black hair on the older vintage and mod Christies has a tendency to oxidize red, which is normal (like on this $295 Talking Christie from 1970). But, if you can find a doll that has retained its original black or brown hair color, those tend to be worth more.

4. MISS BARBIE

In 1964, Mattel tried out a number of new techniques on one particular doll. "Miss Barbie" came in a box set with three wigs to alternately play with, so rather than having the "rooted" hair that is most familiar, she was the first to have "molded" hair—that is, hair painted directly onto the head mold. She was also the first and only Barbie to have "sleep eyes," or eyelids that could close while she was laying out in one of her three pink swimsuits. She wasn't a big seller then, but now a Miss Barbie without all of her accessories can go for $195 (this one, which is in a different vintage dress with none of the original swimwear, is asking $200). However, original sets—those including her three wigs and swimming cap, poolside swing, palm tree, mini magazines, etc.—can command around $1000.

5. VINTAGE "PONYTAIL" BARBIES

The earliest Barbie models didn't have long hair to brush or braid—they had the short curly bangs and elaborate ponytails of teens of the '50s and '60s. The first seven models, released between 1959-1964, were all variations on this look, and any original, Japan-made ponytail Barbie will put you back a few hundred dollars. This #3 in a colorful, custom evening gown is currently going for $725, while this blond "busy gal" #3 that has been partially restored is up for $650. A small subset of this ponytail group? The "swirl ponytail" Barbies, which featured slick bangs that were swept to the side and back into her ponytail. A mint original swirl doll could go for $799, while others are available on Etsy or eBay for under $300.

6. MY SIZE BARBIE

The My Size Barbie craze of the mid-'90s had 3-foot-tall versions that kids could stand up to play with, rather than kneel or sit on the floor. And to pre-program a generation of girls who would later watch marathon hours of Say Yes to the Dress, there was even a My Size Bride Barbie, complete with a bridal gown for 7-year-olds to play dress-up in. Today, many are available for around $150, though some, like this unopened Dancing My Size Barbie, can go for $200 or more.

7. VINTAGE COLOR MAGIC BARBIE

In 1966 and 1967, Mattel issued the extremely groovy Color Magic Barbie doll. She came with either blonde or black hair, and if you used a changer solution packet, her hair would transform to two shades of red. She also sported much more vivid makeup, which highlighted her bright yellow, pink, and blue swimsuit. A blonde one is currently available for $475, and a "Scarlet Flame" (the color the blonde becomes) is also listed for $200. But if you want the whole color-changing solution kit and caboodle, it could cost closer to $700 (though there's no guarantee that the hair will work the same magic as it did 50 years ago).
