NEED LINCOLN EXPERTS (DOUBLE DIE)?

VonZipper

Can anyone tell me if this is the hard to find double die 1970-s or is their a certain place the doubling only takes place? I found this in a roll and have two more similiar to this one just not as defined in the doubling. I provided a couple scans. Thanks

I believe it is machine doubling.

Thanks greg

Do you know if the double die is like the 1955 version where the date is fairly seperated?

The coin you have there is machine doubling, a VERY common problem on cent from that era.

There are over 40 different doubled dies for the date, but the one I think you are referring to would be 1970S DDO#1, which has a clearly visible spread on the date (but NOT the mint mark), the motto, and LIBERTY. It's spread is very close to that of the 1969S DDO#1 you will find photos of in several guides. It is not as wide as 1972P DDO#1, and nowhere near the caliber of 1955P DDO#1. All of the mentioned doubled dies are of the same class of hub doubling, class 1 rotated hub doubling, which has a point of rotation somewhere near the center of the die, which means the spread is about equal on all outer devices.
