GUEST: Just this last Christmas, my cousin was helping my grandparents go through, um, one of their storage rooms, and they pulled this doll out.

It looks like it never had been opened or touched.

And my grandma was, like, "Oh, it's a new Barbie doll."

And she actually was going to give it to one of my cousin's daughters, who's eight.

And I was, like, "Oh, can I come look at it?"

Just from what my knowledge is, I think this could be valuable.

So I was, like, "Maybe hold off on giving it as a birthday present."

(both chuckle) My grandma doesn't even remember buying it.

Probably bought in the early '70s, maybe for my mom or for one of her sisters, so... APPRAISER: What you have is a Walking Jamie doll, and it's called Strollin' in Style.

She's in the Barbie family.

And Walking Jamie was made by Mattel exclusively for Sears.

This was a doll that you would find in the Sears Wish Book.

APPRAISER: It only came out during the holiday season.

And this box just really illustrates the time period.

Um, even the graphics on it are very 1970s.

APPRAISER: And then what's even more fun is when we take the lid off the box, and surprise, look at this.

I mean, it's just, like, Christmas Day 1972 all over again.

Never been out of the packaging.

Still has the original cellophane over her.

And the colors... GUEST: Yeah.

APPRAISER: are so vibrant.

This is a time capsule of the period.

GUEST: Yeah.

APPRAISER: There was one edition before her, it was different colors.

The clothing was oranges and yellows, and the dog was actually gray instead of white.

And they were only made between 1970 and 1972.

GUEST: Okay.

APPRAISER: And you can see Jamie.

She's a beautiful doll.

I mean, she's got a beautiful face.

GUEST: Mm-hmm.

APPRAISER: And she's the first Barbie's friend that they actually used a Barbie mold to create her.

GUEST: Oh, interesting, okay.

APPRAISER: Everybody else had their own mold.

She's got a button on her back, and if you... GUEST: Okay.

APPRAISER: push the button, she actually moves her arms and legs and turns her head.

GUEST: Okay.

APPRAISER: And all this brilliant engineering was done, created by a man named Jack Ryan that worked for Mattel, and he designed the Barbie dolls all through the '60s and '70s.

GUEST: Mm-hmm.

APPRAISER: Value-wise, it's hard to find her because... GUEST: Yeah.

APPRAISER: there just weren't that many out there.

And then, it's just in beautiful condition.

They just rarely exist.

Your Jamie, her retail value would be somewhere between $1,800 and $2,200.

GUEST: Wow.

Wow, that's amazing.

Thank you.
