I would add @Valentinian is of course a seller of good coins. Even better, has some of the best educational articles on his site here: http://augustuscoins.com/ed/ Any new collector is simply irrational if they do not read every single article Warren has posted for you here. I know I read the entirety of it when I started collecting, and reread it every few years for enjoyment. Additionally, our member @dougsmit also has graciously posted articles for new collectors here: http://www.forumancientcoins.com/dougsmith/ Both sites are some of my favorites, and should be required reading for new and experienced collectors alike. They should also be thanked profusely from the hobby for their contributions, which I like to do right now.
