What is the approximate monetary value (private sale) of these two
books? I know the value will depend on the condition of the books,
when and where I sell them, etc. but I'm looking for an approximate
range. Both of them are signed by the author.

Howdy brian22-ga,

These Abebooks entries for the books you have listed will give you a good
idea of the upper range values for them.

"Conversation at Midnight" - $250.00
http://dogbert.abebooks.com/servlet/BookDetailsPL?bi=374432358

"Very Good. Copy No. 92 of the First Edition. Signed. Blue Boards. Brown
cloth spine. Printed paper label. One of six hundred and fifteen copies
printed from hand-set type and the type distributed. Uncut pages."

"Huntsman, What Quarry?" - $350.00
http://dogbert.abebooks.com/servlet/BookDetailsPL?bi=449613904

"Fine/Fine. Limited Edition #316/515. Signed. 110 pages. This is a
superior copy, in the very scarce glassine dust wrapper, and in the
publisher's very good cardstock slipcase with the paper printed title
label stating the copy's limitation number."

This Biblio entry reflects the above pricing for the "Huntsman, What
Quarry?" edition.

"Harpers & Brothers, 1939 Cloth. Limited/Numbered. Signed by Author.
8vo - over 7?" - 9?" tall. Signed Limited 1/551. Number 413
Very Fine copy. No signs of wear.
Great condition of this book of poetry.
$350.00"

I would reckon "Coversation at Midnight" in fine and other conditions
as the copies of "Huntsman, What Quarry?" above could be valued as high
as $350.00 as well.

As you know, condition and things such as the dust wrapper, etc. will
be the final determination of the value of the books.

If you need any clarification, please feel free to ask.
