SO! Which type of mint error do you think is the most difficult to identify accurately? My thoughts are Doubled Die is the most difficult.
Doubled Die falls under the Variety Category. Not the Mint Error Category. There is a difference. Some information.. https://www.ngccoin.com/news/article/1655/Variety-versus-Mint-Error/ And https://www.pcgs.com/news/mint-error-or-die-variety It's good to know and understand the difference.
Parking lot and dryer coins are not mint errors Sal. When you give advice please remember that newcomers to the hobby are reading these threads and they are confused enough to begin with.
Thanks Paddyman98 for the informative links. There is obviously a problem as the first link says that die cracks are a mint error ("Defective Die – Coin has raised metal from a large die crack or small rim break") and the second calls it a variety ("Some die variety examples are: Re-engravings Over Polishings Repunched Mint Marks/Dates And Die Cracks.")
The die rotations in the Diving Goose Dollar range from tiny, that no one cares about and probably within mint tolerances, to very noticeable but less than 45 degrees, and above 45 degrees a diving goose VARIETY with a second axis VARIETY at exactly 180 degrees. There certainly is some confusion here, perhaps mine.
Sorry I missed the joke. Surely a variety is an intentional die alteration and an error is a malfunction during production. Damage occurs in circulation
Where would the clandestinely made or secretively made mint anomalies be identified accurately? A die struck nail for example. Is it a mint error or fake or??? Doubled dies are different that machine doubling and easily identified. Is a MULE coin an error or a variety if only one or two are known ( made clandestinely) or if twenty or more are know? Is it an error when a mint employee pairs up incorrect obverse and reverse dies or is it a variety depending on how many are minted? The posters question, So what type of mint error is most difficult to identify accurately?
