Welcome to the forum.
I, and most members here, are less worried about being scammed than about coins that are thought to be doubled dies, but turn out to be strike doubling or die erosion doubling, which are worthless. You see, probably 95% of the new posters who come on here think they have something special, when, in fact, they have common types of doubling. I am not saying that your coins are not legitimate doubled dies, but I am saying that some clear, cropped, closeups will be necessary before anyone will consider purchasing your coins. Honestly, I hope all of your coins are legitimate varieties, and you are sitting on a gold mine, but they will have to be seen first, to be believed. Good luck.
