Thanks all for the replies! John1 - I didn't realize this was going to be my 100th post. I don't have much time to post so it will be a while before the next milestone, but I very much enjoy being a part of the community!
Albert - thanks for the response! Which books do you know of that discuss these? I didn't see too much discussion on counterfeits in Resplandores, and I know swamperbob is working on a book, but that's all I know of currently.
