The Kovels' top 10 list is based on the results of hundreds of thousands of searches that took place on its website during the month of June 2007.
People use Kovels' price guides for a number of reasons, the most common being that they are just trying to determine the value of a specific item that they own. If an item is not listed on the top 10 list, it does not necessarily mean that it is unpopular or that there is not a demand for it. It only means that in June there was less interest.
