Thank you Rocky, I appreciate that. There is definitely a lot to learn...I'm super intrigued with error coins!! I am unable to send email to you as it says you don't accept them.

There was like 90 million pennies struck this year, in 1959 my guess the presses were able to strike at 200 or more a minute so as a die wears eventually some minor doubling will occur and if you higher mag any coin you will see these minor doubling, the most important thing about this coin is the planchet flaw.

yes I agree this is Mechanical Doubling. but think about this, that coin went through a second full strike cycle... the Mechanical Doubling took place when the coin shifted.


MD is the result of die movement during a single strike cycle:

spruett001 D is the result of die movement during a single strike cycle:
i agree with you completely I worked at the images last night I think I know what happen. I think the die is doubled itself. the strike is a single strike. because that would be the only way the die shows a multi strikes. I measured the the die strikes they are identical. the ditance on the 2 die patterns measure exact. so the die would have to be doubled. so that also would proved it was a single strike. so with that said, there is a 1959 double die out there. I know I am going to start looking for it. have a great one

" Machine Doubling" is really not a "striking" error. In the nanosecond just after the die strikes the planchet, the die or the mechanism that holds the die slightly moves (usually slightly rotates one way or the other)as the die is pulling away from the planchet. The die itself is not doubled on this coin. There are many ways that a so-called "doubled" image can appear on a coin. Here are a few:
