Hello fellow YNs and YNH!Today, I am going to attempt to take a dive into the hardest decision a numismatic collector has to make: which price guide should I buy. Before I begin, let me just say that although I will try to pick a better one, both of these are worth buying from time to time, especially if you buy/sell on a regular basis.The Red Book: 464 pages of awesome coinage. This book is more informational, including pictures of the coins, and paragraphs of important information. The Red Book is edited by the great Kenneth Bressent (my personal favorite when it comes to numismatic publication), and written by R.S. Yeoman. It retailed for $15.95 cents (NOT pennies) in 2020, and is all around amazing. This is defiantly the one you want if you are a more visual and prolific reader, rather than if you want the straight up facts. Comes out yearly.Greysheet: Retailed for $10 last time I checked (though I picked mine up for $5). The Greysheet is the facts and nothing else. No pictures, barely any reading.. this is what you want if you purchase regularly, or are a dealer. Comes out quarterly, which means if a 1989-P Morgan Dollar just went up in value, you will see it in the Greysheet, but not until next year the Red Book comes out.Considering the pros and cons of the situation, I would have to say it is a tie! As I said earlier, if you want to learn pick the Red Book, if you want the up to date facts, pick the Greysheet. What I personally do is get the Greysheet every time it comes out, and get the Red Book every other year. But make your own decision, and I hope this blog helped.Thanks for reading!
