1937 Wheat Cent. DDO? With Die Chip On The Nine.

Not a die chip on 9,looks like damage. Not seeing a DDO either.

Agree, not a DDO.

Could the doubling that I am seeing be Mechanical Doubling?

You do have a very good eye my friend.There are now dozens of wheats attributed with DDO and DDR. First understand a DOUBLED DIE is a slightly miscarved die during the hubbing process therefore making the end result (the coin)hit typically once with a hubbing errored die that permanently changes the elements on the coin until someone discovered it. A Double Die Error is typically machine malfunction as opposed to the result of an out of specification or DOUBLED die.Believe me that once you find your 1st one it is like gold fever and you hit paydirt and can't wait to search some more. I have been searching for the full blown 55 DDO for 50 years and haven't come across her yet. However to me finding 2 1917 DDO's was just as satisfying. Make a cheat sheet with every wheat already ID'ed DDO then go back and study each carefully by using the publication I sent and it won't be long before you are rewarded. Happy hunting

Doubled die are not carved out. They are pressed with a die hub. What dies a hub look like?

The hub is a positive like a coin. The design looks not mirrored like the dies are. (dies are a negative)
The hub has lugs on it and helps keep the die in alignment. These are later removed to machine die die to the correct spects.


But if the hub is rotated, tilted, warped it will affect the die. If a different hub is used, this will also affected the die by doubling some devices. So they are not cut into the die. They are pressed in. In the future they may use lasers to create the dies, bu so far they are not created that way. (yet) They do lasers to frost the dies with computers. They also use lasers to number the dies. So it is soon coming when they will use them. (probably create/prevent hub errors as we know them. Stay tuned. We will see them someday.
