Ok I have a collection of rubble to sell either as one or individual pieces I have an idea of the value of some of the items from a list on the rares collectors forum. They are all from the magincia invasion (original) and not from the quest. There is within the collection a tree stump and as you can see from the picture attached an odd piece that really just looks like dust on your screen which I have highlighted in the pic. This is the only item I have no idea about value but I have also never seen another one before.
Well some of the items have sold I am willing to let the rest go as a bulk deal to the first person with a reasonable offer.
