Which one is better? Got an email saying I could get numismatic news for $30 a year. Do they cover world coins at all?
Yes, NN has articles on world coins from time to time. But it may be quite a while before you find one of interest to you. I have long said that subscriptions NN and CW both should be mandatory for coin collectors. But if what you want is something that carries info with accurate values, then forget it. You're not going to find it in any magazine or a book because none exist. The best resources to find accurate values for US coins and world coins are available on-line for free. But YOU have to do the work to look up each and every one. Of course if you are willing to spend some money you can get access to even better resources to find values for world coins. But you will still have to do the work for each and every one.
