It depends on the situation. If it a rare collection you may have to pay pretty strong relative to the value of the items, on the other hand if you are buying somewhat common or low-demand items then one does not expect to sell them at or anywhere near market value. Often times collections like that will take a long time to liquidate will sell for only a small fraction of what any book may tell you.

At the end of the day a collectible is only worth what someone is willing to pay. Without knowing more about the situation and the types of items being offered it really makes it tough to give a good opinion in this case.
