One example of the good deals is at last years convention I found a $75 Dubuque Casino Belle chip in a $3.00 box. It is very hard for anyone to know the true value of every chip ever made. They sometimes make mistakes. Some dealers think very highly of their material and put top dollar on everything. That does not mean that they won't bargain with you but watch out when trading. They may give you fair market value for your chips against theirs which are priced 30% above market. This said, keep in mind that most dealers are really collectors just looking to get rid of surplus material so that they can buy more chips for themselves.
