Is this a new Lincoln Cent error?

I have not been able to find this type of error. Is it a new DD/RPM?... all comments are welcomed.

Pls. see (reverse) left upper side of memorial building and adjacent columns.

Thanks.

If you are talking about the machine doubling on the edge of the Memorial, no, it is not an error. Not a doubled die, but referred to as MD for Machine Doubling.

 

It looks like machine doubling to me. RPM is an acronym for Repunched Mintmark.

What is the purpose of your poll? I voted for all three.

It was there and OP thought it was mandatory in order to post.

 

I know, and I keep suggesting that Peter include (Optional) at the top of the poll.

Thanks for your help and expertize. Have you seen one before and is it worth keeping?

 

Thanks Chris. Really appreciate your time and response.

 

The system did not let me post unless I selected the polls.

Except for as an example of what machine doubling looks like for future reference, no, not really. You will find a lot more of these in all series as time goes on in your searches. Coin making machinery, like all machinery, needs adjustments from time to time. This is a result of something being loose and needing adjustment.

 

Again, thanks for your prompt response and sharing your expert knowledge. Just learned something new.

 

I believe that only occurs when you accidentally click on any part of the poll section. If you just ignore it in its entirety, it never comes into play.

Thank you for the compliment but I'm by no means an expert. Check Sheila Ruley's new post about her cent, has me stumped.
