i would agree with Herman's estimate on the rubble reagents,with the exception of the dragon's blood and nightshade - those 2 sold to the right buyer ( that being one that perhaps would be trying to complete a set ) are generally more desireable as they "look better"( I don't believe them to be any more scarce in number then the others)However i think you could maybe see somthing in the 15-20 million range for the night shade and maybe 20-25 ish for the dragon's blood.These are prices that I personally have paid for mine - But of course - the only true indicator any items worth in my opinion, is what 2 people agree it is - the buyer & the seller
