Getting stuff accurately valued by someone can be tricky. We do have a 'What is it worth' thread but i thought that was more for those unsure if they want to sell - you seem sure. If you are going to catalogue it anyway, take photos and add all the info to the sale board. Explain that you are unsure (therefore the high price) and that the price still may change up or down for a few days dependant on thread feedback. Start with a high price and insist on a bulk sale with ALL corrospondance in the thread. I am banking on a few members here helping you out on what a good price is. Members can quickly and kindly tell you if your price is far too low or far too high (better to start way high). It would be good to find a box and weigh them to give the east coasters a shipping estimate too.
This is just my thought, a mod may say this is unacceptable practise in the sale section and it may well be, i do not know enough about the caveats.
