A seller in
Coin World back in the 70s and 80s sold these at 10 for a certain price and sent a list of others for sale when you ordered the beginner's lot. None of them were genuine errors that had any value, they were "Spadone" type "errors" that were just common occurrences with cute names for the wow factor in selling them. Over the years I have been in arguments with different people about these "oddities" being "fun" to name and collect. Problem is when beginners get their hands on stuff like this, pay way too much for them, and feel the burn later when they find out their "collection" is just a pile of pocket change to 99.9% of all collectors. The market is what it is - I don't make it, I just report what I know about it. And what I know about it considers this stuff pocket change.
