Hello,
I'm confused.
Error coins are not to be listed in the catalog. They can be mentioned in the comment field. That is what the guidelines state.
There are however a number of errors listed in the catalogue with their own date range. I remember going over the catalogue but I don't remember this rule, will look over.
Oh, there are. I was recently asked if one that already existed should be removed I answered, “Either that or modify the guidelines to address when exceptions are allowed. Otherwise every country/referee can do whatever they want however they want. Inconsistencies in a catalog make them less reliable.”
Here's the guidelines on mint errors:
Variations of a coin
Variations are random or unintentional differences in the physical appearance or properties of a coin that occur during the minting process, after the production of the die. For example, mint errors, random alignment or edge orientation, slight variations of the planchet in weight or size, different colouration of the alloy, etc. These are common for ancient and medieval hammered coins. Error coins are also variations.
In the Numista catalogue, the variations are not listed as mintage lines. They can be mentioned in the comment field. By exception, mules are listed in the catalogue as separate types.
Two famous ones are the US 1943 Bronze penny and the US 1944 Steel penny. My comment above also applies to these.
