Is it worth parting out a set to sell without the minifigs? I wanted to sell my Lego in a bulk, but then decided I don't have a reason not to sort it out.

I do believe I have the Ninjago Earth Dragon (2509), but before I find the pieces, I know a few things about it's condition immediately.

The bricks are good. I've never had problem with the treatment therefore no scratches or broken stuff.

There are NO minifigures or accessories (I sold all my figs in bulk for 20 dollars a while ago, I know I am an idiot)

There is no box or instructions... Just the bricks. Is it still worth the effort?
Not having the minifigs certainly hurts the value of a set, but it may still be worth parting out the set depending on how valuable your time is to you.

If you haven't already done so, you can use the Price Guide feature on Bricklink to get a rough idea of what your set can sell for.

You can also browse the current listings for the set to get an idea of how much missing minifigs hurt the price. For that set, it looks like not having minifigs knocks off about 40% of the value of the set ($24 USD vs $42 USD).
