Are those publishers okay with copyrighted material to be duplicated like that? I understand fair use and all but 4 pages like that from a recent book, I'm not so sure.
Looking for Top Pop Mercury Dime Varieties & High Grade Mercury Dime Toners.
i feel ok about it citing the source for public non-monetary use.
added: i'm pretty confident they don't own that information as it is public and on the mint's website. someone posted link(s) over the years here.

Thanks for sharing.
