What kinds of things are actual errors? is there a list of possible errors? I figure with how long people have been looking there must be a somewhat finite list of errors for different processes?
I would really like to know:
1.What types of errors are there?
2.How do you search when YOU look for these errors?
I want to make sure I don't miss things when I look through coins

Many people collect a certain "genre" of errors, like MAD and planchet blanks, or RPD and RPM, or maybe double strikes and clashes. I've focused on IHC varieties, which are primarily RPD, DD, and design "errors". Edited by Drsandman2

I use a 16X loupe and there should be only once source of light. If you have light coming from different directions you'll see doubling every which way but it is just glare.
Happy hunting!

That's an easy one.
Somewhere in the production line a dime planchet got mixed in with some quarter planchets, it might have been left over in a bin or stuck in a machine and fell out later, who knows...
Any error of this type is possible as long as the planchet being struck is smaller then the dies it is going into, in this case a dime planchet that went through the quarter dies. What you can't have is an error the other way around, you'll never see a quarter planchet being struck with a dime or cent dies, it's to big to fit through.

Having an understanding the coin minting process aids in the determination of what can and cannot happen that makes an error coin. A lot of the coins found on the auction sites play on the lack of education of some collectors. Novice collectors spend a ton of money on coins that are not errors eg. hammer jobs, coins with road rash or coins with outright damage. You see a lot of questions on the forums asking if something is an error or not and most of the time the answer will be PMD. Actual errors garner nice premiums because they are rare and not found everyday. It can be disappointing to a roll searcher when every suspected error coin is shot down but that is just part of the education. |

If you look and search at Coin Fact Encyclopedia/PCGS/Errors:COIN FACT ENCYCLOPEDIA/ERROR: A DOUBLE DENOMINATION RRORS One of the most expensive, popular, and desired types of errors are the double denominations. This error happens when a coin is struck on a previously struck coin of another denomination. Examples are a cent on a struck dime, and a nickel on a struck cent. The most dramatic are those with considerable design visible from the original strike. You will find this one and other errors such as transitional, etc. Here's one example of my double denomination same year with two full dates obverse. ![Ok,-So-I-See-A-Lot-Of-]( "Post Mint Damage") PMD"-As-Replies-Here,-What's-Real?" class="userimg" style="image-orientation: from-image !important; max-width:80%;height:auto" name="img" src="http://www.coincommunity.com/forum/uploaded/elevencents11c/20120908_1995PENNYONDIME-OBVERSE.jpg" border="0" style='cursor:default' onClick='doimage(this,event)'> |

Hey Broseph. You have to learn the minting process to become decent at error collecting. I learned a great deal from Alan Herbert's book MINT ERRORS. I have the sixth edition April 2002. Not sure if there is a later one. Get a good 7x magnifying loop. I read that if you can't see a detail in 7 power then don't bother.

I would also recommend Alan Herbert's book Official Price Guide to Mint Errors, now in its 7th edition. The title is a bit of a misnomer since the valuations are very generic with no regard to denomination, series, or year. The book utilizes the PDS(planchet, die, strike) system of error and variety classification and describes hundreds of different kinds with example photos included for some.
