Good Catalogue?

Welcome to the forum kysim. I would recommend what most people will just call "The RedBook", by R.S.Yeoman for your coin types and values. For grading purposes I recommend Photograde by James F Ruddy, and the ANA guide to coin grading. Sorry , don't know the author of that one.

I would also recommend just simply spending time here and reading the threads. Ask any and all questions that you have. There is a lot of info on this site in general. Browse the links on the left. There is a great coin facts section here. You can also type in a coin name into the search engine up top of the forum and you will get fantastic results.

There are lots of publications out there, and you're going the correct path by buying and reading books prior to spending your hard earned money. The local public library is also a great source.

Welcome to our CC family!

The PCGS price guide is considered to be very high. For the most part, even coins graded by PCGS don't sell for the values on the PCGS price guide.

I moved your topic to the Main Forum. You will see more traffic there.

Welcome to Coin Community, ksyim !!!

The RedBook is probably the best for starters. It gives pretty good information on all US coins, but the prices can be up to 18 months out of date in some cases. The PCGS price guide is fairly useless. A terrific way to check coin values is to use the Heritage Auctions website archives. You have to sign up to become a member (it's free), then you can access the whole site.

Mostly already said by everyone. Start with the Red Book for information but not prices. If you want prices, try what I do. I make a list of some coins I may want to buy. I then make several columns and start a price search for those coins. Yes the PCGS web site is one place. Column 1 price. Red Book column 2 price. Then hit several dealers web sites such as MillersMint for their prices, column 3, etc., etc. If you stick with these coin forums you will find numerous locations for coin prices and make your own list of what a coin may be worth.
What I really suggest is going to coin shows. Try Coin World, Google, Yahoo for listings of coin shows. If using Google, just type in coin shows and your state. Hopefully there are some in your area and you can make it to them. Nothing like hands on experience in coinage. You can find all the prices, grades, coin books and albums on the internet but the real place to learn is at a coin show. If I said a coin is worth a million dollars but at a coin show you see it in person and it is selling for five dollars guess which is correct.
