When searching for series books, I have always operated under the thinking that a book without it's dust jacket is worth very little. Many series books that are are missing their dust jackets are very hard to determine their printing points, mainly because publishers like Grosset and Dunlap did not update their copyright pages, and often times ads for other books were not changed regularly. As a result, many collectors pass on books missing their dust jackets.
This has led me to wonder a bit about the worth of older Nancy Drew titles. Older thick blue volumes without dust jackets seem to be little easier to find these days on Ebay, and they are certainly less expensive than their jacketed counterparts. I am inclined to think that they are not very sought after by collectors, thus their prevalence on the market currently.
I understand why they are not as collectible as volumes with dust jackets, but I wonder if people are not missing the boat. Many of these volumes are still attractive and holding up well. Endpapers are bright and attractive, and the paper quality on 1930's volumes are often times still crisp and white. A few that I have found recently feel as though they have hardly been opened. I had the good fortune of finding a few of these on a recent visit to some antique stores. Examining these early volumes, they seem to be worth having in one's collection. Finding a early printing without endpapers would be even more exciting.
I'm curious what others think. Is it worth picking these older printings up, dust jacket or not? Will we see a rise in value for these volumes?
