Cost of my books

[chanell9]

I have 5 editions of War with the Boers in good condition. What are these worth?.

Do you mean a single book in 5 volumes?
A 5 volume set, not in top condition, was sold at auction in the US for $588. See here. (scroll to near bottom).
Single books from the 5 volume set sell for about �15.
Two volumes from the set of 5 are on offer in the US for $40.
