If you like some advices...
TH RF set- I am offering it now for 300$ (but its lacking 3 not very important cards - quickbeam, eomer, attea) and I have a LOTS of offers. So probably its wise to go for $400 and higher.. I believe that $500 for MINT set is ok.
RoS - contains some cards that can bring you much more when sold as singles because they are extremely valuable (Saruman,
warg,
shadowfax etc..) And I dont thing that selling the whole set is so hot for anybody since sellers ask too much often.
So I would maybe consider looking for people who want to pay nice cash for singles and than selling the rest as an uncoplete set on ebay.
TD - the same thing as with RoS
