Anyone know anything about Britney Spears dolls?

I found one thrifting with my aunt this week while she was visiting from Florida.  Well, I found two actually, but the "other" one was easily identified and valued.  Not worth much.
The one I'm asking about seems to be rare.  The only listing I could find for her, was a completed one that ended at a little over $100  

Mine is also MIB, although the box is a WRECK, and I kinda cut the tape to open her before I got the bright idea to see if she was worth anything first   I wasn't expecting to see a hundred dollar listing!

So, any advice?  I sure could use $100
