Zane Grey collection

I have what I think is a complete collection of Zane Grey books and
stories. This was printed sometime after 1979 and is in near perfect
condition. There are 65 books in total, plus two duplicates. They
belonged to my father-in-law who recently passed away and his wife
asked me if I would find out what they are worth. Any ideas? Feel free
to email me privately at ... thanks

If you'll check bookfinder.com, you'll see that individual volumes go
for anywhere from $6-7 each to close to $30. Some of the titles are
just about the only available hardcover, and at least one is a first
edition. This set's not complete, so the value will depend on where
and how you sell it. See this site for more info:
