I decided to take note of some of the recent eBay auction prices for the Outdoor Girls and Blythe Girls books. There has been some very competitive bidding recently for the Blythe Girls books.
Blythe Girls:
Helen, Margy, and Rose w/DJ, $9.99 (Buy It Now), $88.76 (auction)
Margy's Queer Inheritance w/DJ, $77.76
Rose's Great Problem w/DJ, $40.88, w/DJ $4.99
Helen's Strange Boarder w/DJ, $21.50
Three on a Vacation w/DJ $7.45, w/DJ $21.18
Margy's Secret Mission w/DJ, $90.89
Rose's Odd Discovery w/DJ $97.89
Snowbound in Camp w/DJ, $39.88
Margy's Mysterious Visitor w/DJ $39.99 (Buy It Now)
Rose's Hidden Talent w/DJ, $191.38
Helen's Wonderful Mistake w/DJ, $84.00
The prices realized for different series books range from low to high, depending upon how many people are interested at a particular time. Consequently, some of the books sell for well below value, since many sellers choose to start the books low and sometimes only one person is interested in buying a particular book. This is why a few of the Blythe Girls books sold for fairly low prices as compared to the other books. It is also not a good idea to use Buy It Now when selling a book, unless one is very certain of the value. Compare the Buy It Now price to the completed auction price for the first title in the Blythe Girls series.
Outdoor Girls:
Outdoor Girls on Pine Island w/DJ, $34.99
Outdoor Girls in Florida w/DJ, $16.07
Outdoor Girls in Army Service w/DJ, $36.55, $20.50
Outdoor Girls Around the Campfire w/DJ (Duotone), $57.99

Outdoor Girls on a Canoe Trip w/DJ, $29.88
Outdoor Girls at New Moon Ranch w/DJ, $8.99
Outdoor Girls in Desert Valley w/DJ, $325.00
I believe it has been quite a few months since a dust-jacketed copy of Desert Valley has sold, so several people very much wanted that book.
Girl Scouts Mystery Series, The Mysterious Camper w/DJ, $87.99
Girl Scouts Mystery Series, Trail of the Gypsy Eight, no DJ, $24.83
Girl Scouts Mystery Series, The Secret of Halliday House; w/DJ $93.00; no DJ $18.50
