1935 D Lincoln Wheat Doubling Question

Well first cents minted in this year are not plated, so no this could not a problem related to any plating. And perhaps you could post the reference site or material where you read about "Plating Disturbance Doubling".

Thank you for the reference, many people show up here (and other forums) having read about or heard of a term or effect but not really knowing what it means. As you can see from that article this effect happens on the zinc core copper plated cents that were minted from 1982 to current. Cents prior to 1982 (including your 35-D) were solid alloy made mostly from copper. As those coins were not copper plated they do not suffer from the many plating/striking issues that have plagued the zinc core cents like that shown in this error-ref article.

What you see on your coin is die deterioration, the mint has always overused the dies for circulation coinage to get every cent of value from a set of dies. As the die approaches the end of its useful life many times it has become so worn that the edges of the letters and design elements are no longer sharp and metal squeezes out at the time of strike. When that happens you get a mushy look to the letters like you see here between the letters and the rim. Add to that the significant wear this coin has seen while doing its job in circulation.
