So I decided to peruse through my penny books today and couldn't quite figure out why this 1940 penny reverse looks the way that it does. I'm mostly familiar with the "woody" Lincoln's and why they show the wood grain look but this one just looks... different. The obverse doesn't appear to have the same effect as the reverse, so I'm kinda stumped. Anyone care to elaborate or explain what would cause this? It looks more like tiger stripes in person than it does in the pictures. Thanks!
That's considered a early stage of Progressive Indirect Design Transfer Aka - Ghosting Information here - https://www.error-ref.com/progressive-indirect-design-transfer/
Thank you! But where is the design transfer coming through? The reverse doesn't seem to show anything related to the obverse.
No, I don't think that is what's going on here. With PID Transfer, you get a ghostly image of the other side - you'll see Lincoln showing up in the middle of the wheat stalks. In the OP's case, they show wide parallel stripes, not an outline of Abe. I believe what you show is a rolling issue - when the planchet was rolled, there were some errors in the rolling process. Unfortunately, error-ref doesn't have images or an article linked.
