Welcome to Coin Talk. Hope you stick around. There's a lot to be learned from the members on this site. One thing you'll learn is not to put too much stock in anything about coins you see on you tube.
I’m new to the coin collecting and want to learn as much as I can! Besides the price books, what are good sites I can get info on coins that I come across?
