Are LEGO boxes worth anything?

LEGO boxes can be worth something based on their condition and theme. At a minimum, every LEGO box is at least worth using as cardboard or recycling into new paper products. For instance, cats and kids like to play with empty cardboard boxes. Cardboard boxes can be reused to store items, or even collapsed and used as padding between items when moving or shipping.

There are also marketplace sites like Bricklink that facilitate selling LEGO boxes to hobbyist and resellers that will then use the box to complete a set for their collection or to increase its value for resell.

Here is a link to box categories by theme:

LEGO boxes can be worth hundreds of dollars for sets that sell for thousands of dollars.

If saving boxes for collecting purposes or resale, you must decide if you will store them collapsed or in box form. Will you store them in a black plastic bag with a moisture desiccant inside? Will you store them in a temperature and moisture-controlled environment? 

You may also be able to donate the LEGO boxes you are no longer using so they do not just go in a landfill. Some hobby stores that resell used LEGO sets will accept the boxes as donations and try to use them again.
