They are expensive because they were either signed and numbered first edition or because they were autographed upon meeting Pleasant Rowland. So they are very rare.
Some collectors prize this sort of piece, so if you are that type of person, then yes it is worth it.
To me it is not worth the money. My collection is not of first editions and white bodies (although I do wish my Kirsten was white body, since she is pre-felicity). I would not pay this sort of money, I would rather have $500 of accessories and clothes (although I wouldn't get that either.)
Board members have bought these dolls and said they were worth every penny.
