asked

I have two Hardy Boys Books, 'The Secret Warning' (1938) and 'The Ghost at Skeleton Rock' (1957), and I want to know their value. The books are in excellent condition with no bent or torn pages, but the spine on 'The Ghost at Skeleton Rock' is slightly damaged. There are no dust jackets, and they were published by Grosset & Dunlap in the U.S.
