Buyer Confusion on Nancy Drew #13

The goal of this series of posts is to educate buyers on how to avoid unnecessary questions. Here is another listing in which a buyer asks an unnecessary question:

8 Early Nancy Drew Nos 1-18 DJs Blue Orange Keene G&D Item #350088683302

Question: Hi, Do volume #'s 1,5, or 7 have 3 glossy internals, as well as the glossy frontispiece?

Answer: Just the frontpiece. I don't see any internals on a thumb-through. Thanks for looking.

In the item description, the seller states that #1 lists to #16 Tapping Heels on the front flap; #5 lists to #19 Missing Map on the front flap; and #7 lists to #18 Moss-Covered Mansion on the front flap. This information is enough to indicate that it is highly unlikely that the books have the additional internal illustrations. Since only the first 13 titles were printed with the glossy internal illustrations, the volumes that have the glossy internal illustrations list only up to #13 Ivory Charm on the front flap. Any book that has a dust jacket that lists to #14 or higher on the front flap does not have the glossy internal illustrations unless the book and dust jacket are grossly mismatched.

In the unlikely event that a book with internals has been mismatched with a later dust jacket, there is no increase in value. If anything, the mismatch decreases the value. The vast majority of collectors who seek the books with internals and intact dust jackets want the books to have the matching dust jackets that list to #13 or lower.
