So i have the 2007 ultimate collector series and my Box have been water damaged When the place i had the Box was elaking water. I have i have all of the pieces in a big bag and i would like to know if i ahould sell it now or later. Incase i should sell it, for how Much?

you need to specify what set. Depending on when you sell it, the price may fluctuate a bit. If you want to sell a loose set, it is best to assemble it to show your buyers how complete it is. If the bags are original and still sealed, that should be ok if you can verify that the number of bags is correct. Are the stickers present? were they damaged? Are the instructions present? were they damaged? all of these are things that will influence the value.

The thing is that i was very young When i first got this set. The set number is 10179. 

The pieces are not sealed and i dont tthink the sticker is present.

I Do think the instruction are complete

Were the instructions damaged by the water? The value of this set has been going down, but if it's complete, or even if it is missing the sticker plaque, there's still some money to be made. Not as much as 6 months ago. verify all parts are present before you try to sell it. If they are missing, either try to get the parts, or write up a list of what is missing and let your buyers decide.
