Well, there has been a little controversy lately, but overall I assume it's not a bad venue. Selling the entire collection, correct? This might be the best place if your not comfortable with the "bay" and their fees.
I have had not one problem buying or selling on CT its all in how you approach it, just be smart. I tend to like using Pay-Pal as a form of protection.....
I've bought/sold some stuff here on CT and have had nothing but a good experience. I would say that I prefer it over other methods.
I have too much stuff to sell on the BST's but given your well documented buying experiences on E-Bay, you should be able to become a very successful seller who is able to avoid all the pitfalls that frustrated you as a buyer. Give it whack. What is the worst that could happen?
If you name a fair price and other's trust you then everything should go smoothly. I've sold at least 5 to 10 gold coins with no problem at all. In fact I may list some more stuff soon.
I sell coins here every week, only problem i had was with hcsc, never got my payment. Other than that it has been awesome.
