Are you buying these coins to resell or to build a set? If its the later like I am usually doing them I don't ever worry about paying a little to much. I pay what I think the coin is worth and put it in the set I bought it for and forget about it. I will do my research and see what others have sold for high and low and try to keep what I pay somewhere between the two but I don't ever worry about if someone else thinks I paid to much for the coin as it was bought to bring me enjoyment and that is what it has done. I don't even ask anyone what they think a coin I have purchased is worth because the same coin will be worth a different amount to different people. The ones that has one will not be willing to pay what someone that wants one will pay, so as long as I am happy with the purchase then that's all that matters to me. So I wouldn't worry about if everyone thought you paid to much or got a good deal as long as you were happy with it
