You are probably not going to find much of a market for the proof and the 2002 - 2006 as there is not much of a demand for them. At current silver spot you can look to get about 1.65 each for the 40% and 7 1/2 to 8 times face for the 90%. The dealer will not care if they are walkers, benjis or kennedys, he will pay the same for each. You might want to make sure you do not have any scarce dates in there as far as the walkers and benjis go.
