Value of old books - Hardy Boy and others

[Dilts15]

We are looking for some direction/assistance in determining the value of 1930/35, etc. Hardy Boy books. There are others as well- My Friend Flicka/1941, Black Beauty, Readers Digest Condensed Books, etc. It is our intention to sell them. Thanks for any suggestions.

According to Ebay.com, a complete set of Hardy Boy books (58 books) can be purchased for about $320.

If you're on eBay, you can use the advanced search tool to look up what these books have sold for.

We donated an almost complete set of Hardy Boys books to charity. These were mostly blue covers, but a good few were brown covers.

Did a quick search for value at the time and it wouldn’t have been worth the effort to try to keep or sell them.
