When dealing with antiquarian or collectible books, condition plays a major role in the resale value. Collectors are looking for top quality issues with the least amount of damage. Soiling, staining, binding damage, cover damage, or torn pages would result in a drop in value.
In the current market, your 1938 edition of the Trilogy of Studs Lonigan, by James T. Farrell would have a resale value of 20-25USD in good to excellent condition.
Taking into account the damage to the cover, a realistic resale value would be closer to 3-6USD, if you were to attempt to resell the book yourself. These old books can be a tough sell when damaged, due to the amount of money it costs to repair them. Which many times is more than the book itself is worth.
I hope this information was helpful to you today.
Best of luck with your vintage book.
