When a trilogy (or any number of books in the same series) gets a limited lettered and/or numbered run, does having the same letter/number in all of the books increase the value of it?
Thank you for your time,
In response to your question.
"I don't think so."
We have a lot of customers who collect the same number or letter in a series, but I have found no evidence that such a feature increases the value.
Limited edition sets are usually assembled when a third or final book is published in a series. At that point, the publisher pulls from remaining stock to assemble the set. But do take care. We recently bought some set of a Ken Follett series (in a signed box). The individual books were not signed, and one of them wasn't even a first edition.
Hope this helps.
