Oh, the good old days. You'd rush home from school to make sure your Tamagotchi was fed, the most important part of your day. You would frantically try to find batteries around your house so your Furby could still make those weird noises. Your American Girl doll was your BFF and she never left your side. You two were inseparable.

Those dolls were really such a treasure for anyone who owned one, and now, they're even more of a treasure — the kind that makes your wallet fatter.

If you still have one of your old American Girl dolls, you're about to be overjoyed. These dolls are selling for large sums of money. Like a fine wine, these dolls age well, even though they stay forever young. From a few hundred dollars to a few thousand dollars, many American Girl Dolls dolls are a gold mine, so let's hope you decided to save your doll (and hopefully not give her a weird haircut with nail clippers).

A new beginning

In 1986, the first American Girl doll was released, made by a company called Pleasant Rowland. The original dolls were: Samantha Parkington, an orphan being raised by her grandparents in 1904 New York City (archived in 2009 but re-released in 2014 as a BeForever doll). Felicity Merriman, a Revolutionary War girl living in 1774 Williamsburg, Virginia (archived in 2011). Kirsten Larson , a pioneer girl originally from Sweden, living in Minnesota in 1854 (archived in 2010). Molly McIntire, the daughter of a WWII doctor who has gone to Europe to help wounded soldiers (archived in 2014). Josefina Montoya, a Native American girl living in 1924 New Mexico with her father and sisters (still available). Kit Kittredge, a Depression-era girl living in Cincinnati (still available). Addy Walker, a young girl living on a North Carolina plantation during the Civil War (still available).

Your own mini me

Years after the original dolls were released, the company decided to embrace the unique qualities of each customer by offering customization. They wanted each girl to find a doll that they looked like.

The books

Each doll came with its own book as well. The story revolved around the doll and her perspective, including talking about where they came from and what kind of adventures they lived through. It was a cute and creative way to make the dolls seem more real. They wanted to create "Strong Characters, Powerful Stories" as their website proudly states.

Serious stuff
