=== Variety vs. Mint Error | NGC (ngccoin.com)
Even the NGC definition has some problems. Their use of the word "design", for example, introduces some ambiguity. Basically if a feature on a coin exists on the die, and the coin is otherwise free of strike or planchet errors, you cannot have an error.
I disagree with their implied categorization of major die cracks as errors while minor die cracks are not. A die crack is never an error, as a crack can be present on hundreds of thousands of coins as it progresses. Those are obviously not all error coins. These are just features of die use, and are no different than the general signs of die wear on the legends and devices, which they correctly do not call out as errors.
The way I think of it, an error is a one-off occurrence that happens to a particular coin. You can get a similar error on another coin of course, but it is also a one-off. This is in the same way that two people may trip on the same part of a sidewalk at different times; there is no relation between the two accidents, though they may be extremely similar. On the flip side, any feature imparted to a coin under normal operation that is then imparted to the next coin, etc. and is consistently repeatable, is not an error.
An error is a one-off accident during the coin preparation process. Each error coin is technically unique.
A variety is an accident involving the making/abuse of the dies themselves. Each variety had multiple exact copies struck before the dies were taken out of commission.
...no...the die made repeated copies of the variety before the die was retired...Spark
Therefore, wide AM and close AM are errors? Not trying to nitpick here. INtersting to see something so 'basic' to the hobby is so contested.
No. They are varieties. Their position on the die was intentional.
A mint error is an unintended deviation of the coin design that can be attributed to and origins traced to the manufacturing process of the coin.
A type is an intended deviation/change in the coin design.
Is it though? Minor intended deviations of the coin design are frequently catalogued exclusively as varieties and not types.
