such. Thank you very much. No matter how many times I see the difference between machine doubling and a double die, I still don't get it...lol
with a real doubled die, the secondary image has the same rounded relief as the primary image. for example, this trade dollar: Note that the tips, or serifs of the letters and numbers are split (doubled) as well as the points of the arrows. You don't usually see split serifs on strike doubling. Hope that helps.
These pics are from a 1922 peace dollar that I thought was double die. I guess this is machine die too? Thank you for looking.
A double die actually occurs because someone tries to repair an existing die, and the repair is superimposed onto the coin?
No. Doubled Dies happen during the die making process. No repair is involved. There is a ton of info on the internet about how they occur and how they are made. Quick tip. The doubling on a genuine doubled die coin is virtually at the same level as the design that is doubled. Note that the double looking design on your coin is not. One image is lower than the other. Additionally, authentic DD coins will have a notch at the tips of the doubled design elements (numbers, letters) or the doubled design (dress fold, etc) will be right next to each other.
