So why do the Doyle and Magie errors counts as part of the set?

why isnt nodgrass included then?

i think it is because there are so few of them, and if it was unofficially officially included , the price would skyrocket for all of the unofficial official set collectors would now have to have one. if there were 300 nodgrass errors in existance, it would be okay, but there are only ? so people don;t want it added to the unofficial official list because it would just be another card to go for big huge bucks, and the set is expensive enough already.

Items like “Nodgrass” aren’t included because like all of these font screw ups. They are nothing more than a card that had something get on the plate during printing that caused a letter or part of a letter go missing.

Whereas Doyle and Magie were mistakes made and the original plates were changed to reflect a correction to the typo. Then the cards were printed again in greater quantity with the typo fixed with the plate changes.

'nodgrass' wasn't intentional - it was just crappy production. If you include 'nodgrass', you have to include all the other crappy problems that ended up in packs.
