Has either push, slide or ejection doubling on the nose, mouth and chin. I guess is slide doubling. https://www.error-ref.com/slide-doubling/ "We are all flawed, some MD and some PMD."

Dutch-Tigger Valued Member United States 301 Posts	Posted 06/26/2023 9:54 pm @DearBorn , I am feeling the same on this due to lack of a Smear with striations along the affected area. All Slide Doubling Iv'e seen had an Off Center Strike as well due to the shift of the die. Would like the affected area to be shot with a little more light to see if there is as well a Step for a possible Push doubling. Very nice coin to keep for its Oddity Edited by Dutch-Tigger 06/27/2023 12:19 am Report this Post to the Staff
Brandmeister Pillar of the Community United States 6464 Posts	Posted 06/27/2023 01:55 am Odd that the IGWT doubling is headed in the opposite direction from the face doubling. Report this Post to the Staff
mikediamond Pillar of the Community United States 2734 Posts	Posted 06/27/2023 09:40 am This would be slide doubling. Metal has been pushed up by the sliding obverse die. It is possible to have Machine Doubling that combines both push doubling and slide doubling. A die can bounce, shift laterally, land lightly on the newly-struck design, and then shift sideways in the same direction. It's also possible for the hammer die to lift up slightly before sliding. This can create a low shelf and piled-up metal. In classic slide doubling, the hammer die remains in contact with the field at all times as it slides to one side. Error coin writer and researcher.

NY Islander Pillar of the Community United States 978 Posts	Posted 06/27/2023 11:07 am @mikediamond Thanks for the confirmation on the slide doubling. It is dramatic and the images don't do the damage justice. Cheers! "We are all flawed, some MD and some PMD." NYI Report this Post to the Staff
