I can try and help, but I'm not sure what most of these items go for:
1. Wanderer Track (If i remember correctly, they go for 10-15mil? I know that its worth alot because its the rarest track you could get)
2. Not sure
3. 500k-3mil (Give or take a few mil but I THINK thats what they sell/sold for.)
4. Not sure (Isn't this an event item?)
5. Not sure
6. 5-10mil? (I know this isn't the server birth one but I think its rare, If i remember correctly 5-10mil is what they sell for)
7. Thunderz was talking about the regular double exceptional, no way is he picking these up for 500k-1mil (If he is, lemme know where) these are bracketed. (The rarest version.) I say 7-15mil. Give or take a few mil, I know for a fact there are collectors who collect this stuff. (Queen Arya)
8. Knowing they were worth about 2500-5000 points per stone in the clean up. There aren't many left out there. That is a guess, don't quote me on that haha. So i say a full set is VERY rare and can be worth quite a bit to the right person. The price, I'm not certain.
I'm not sure if my price checks are accurate but they are somewhere around there. I hope a expert on these item can post the accurate price. I hope this helped and I wish you luck selling them.
