I just became a platinum ANA member, i have a vending business and go through over 1000.00 each week in coins and paper money. I have been collecting coins for many years and started researching them and errors within the last year. If anyone can tell me where to start and how to have my coins graded, which ones to have graded, how much that costs, suggested coin selling sites and any selling tips, whether to sell a large lot at once or 1 coin at a time. Any and all information, guidance and help would so greatly be appreciated.

you can send coin for grading to the NGC I think

Welcome to the forum. I have only been collecting for a short time, less than two years, but the best advise I have gotten is get the book before buying the coin. What I mean is get a Red Book. The 2019 is out soon. Get a general idea of how much the coin is worth. You don't want to grade a coin that is only worth 50 cents and pay 15 dollars to do it. If you have a coin under $500, I would use ANACS. I have not had any problems with them so far. with coins over $500, you may want to consider NGC or PCGS. They are the two top graders and their opinions hold more value, in my opinion. As for selling, I am not versed very well to be giving advise. I have sold a few coins at my local clubs auctions. I traded a Morgan worth about $250.00 for an entire set of WW II Airplane coins. Good Luck to you.

I would pick up the cherry pickers books for one and two.. They show the variety and price. But condition is everything. Your not going to send in a 25 dollar coin it will cost more to grade than its worth. So be careful. 

I only recommend PCGS (shooters preference).  Get ready to fork out $40 for the grading and slabbing services.  I would only recommend submitting coins that have the potential to be valued at $200 or higher.  I disagree with only slabbing coins valued at $500+.  No savvy investor or collector (myself included), would ever allow a coin with that kind of value to be an "unknown" specimen.  I would also never buy a coin of that value unless it was PCGS slabbed/with bar code confirmation.  Too many fakes, bad-graders, counterfeiters, and scammers out there.

Invest in your own grading standards book.  The Official American Numismatic Association Grading Standards for Untied States Coins, by Kenneth Bressett is a great resource.  Invest in a 4-6 year old Red Book if you can't afford the monthly Grey Sheet subscriptions to see what the retail value of the coin is.  Always check Ebay for selling trends of your coins.  Especially slabbed versions of your coins.  Don't focus on the bidding amounts, but what the average price of your coin type was SOLD at.  Then you will have a better idea of whether or not you should invest in getting your coin graded and slabbed.  I also recommend typing in some of your questions on YouTube.  There are a lot of great short videos on this very topic from passionate collectors willing to share their knowledge.

I would go with ANACS for the lesser known and cheaper varieties. If you find a rare coin, PCGS and NGC are your best bet. Good luck and happy hunting!

The good advice is the grey sheet. Many yns and collectors do not know about. It tells the dealer what he should ask for a coin. If your on the Registry Set at NGC they tell you the price of the coin you entered. There are many reasons to slab. One its s sentimental. Two you like the coin or token and want to keep it that way. We all collect for different reasons as long as your happy thats all that counts. Thanis for the thread.
