Breeches Bible and John Bunyan book

I don't know if this is really the right place to ask, but I have a 1615
edition of the "Breeches" Bible, in good condition apart from the cover,
which is hanging;  I also have a 1752 edition of "The Holy War" by John
Bunyan, and wondered if anyone could tell me whether there might be any
value in them. Any info at all would be appreciated. Thanks.
