Error Type Collection
This is my attempt to create a basic type set of error coins. I am convinced that the best way to understand these coins is studying verifiable examples. I have been collecting, off and on, for probably 50 years or so. I don't consider myself an expert in the field, but I have learned a few things along the way. The categorizations are strictly mine and I'm sure make the experts whence in pain. If you have an interest in this sort of thing I would strongly suggest you spend some time at the best site on the web for technical error information - The Error -Variety Ready Reference. This site could be useful for viewing examples of most known major types.
My preference in errors is one error per coin. This is not always possible, so I have classified each coin based on what I consider to be the main focus. Coins containing multiple errors can make for interesting discussion and research, but they are just not of great interest to me. There are a few discussion boards on the web and I strongly recommend Mike Diamond's Error Coin Information Exchange. You can learn a lot there.
