I think as far as in a ratio of timely information to advertising, Coin World is the best publication going. Numismatic News has mintage information not available elsewhere, but IMHO has very little in the way of actual numismatic NEWS. If you aren't watching your dollars as carefully as some, subscribe to both of them. I think that they are both excellent publications.
Numismatic news, banknote reporter, and coins (although i will be letting the coins mag die when the subscription comes up)
CoinWorld. If you like varieties then you might check into joining CONECA---they sent out a mag. every other month that is pretty good. Also if you join the ANA you will start getting a monthly mag.....but in most cases by the time they print the news it has already been known for awhile because of others like CoinTalk or NN. Speedy
