There is an alligator under my bed resale value

There is an alligator under my bed by Mercer Mayer (1987). Across 16 editions. Used-book value depends heavily on edition (first printing vs. reprint), condition, dust jacket, and whether it's signed. First editions and out-of-print titles command the biggest premiums.

What drives the price

First editions/first printings, intact dust jackets, signatures, and unmarked pages are the top value drivers. Book-club editions and later reprints are worth far less.
