Can someone explain "Die-Suction" error?

That isn't rare. Most well struck Lincolns have them. I believe it's caused by metal flow on both sides of the coin.

There's no such thing as "die suction". What you're seeing is a case of progressive, indirect design transfer -- a form of die deterioration. It's quite common on wheatback cents.

Die suction is an ooooooooold term that truly means nothing.

CaptHenway

When dies strike coins, the various recesses in the dies that make up the designs cause differing pressures to be transmitted through the planchet to the opposite dies. This causes uneven wear patterns that can eventually simulate the design of the opposing die.

It’s the term given to the sound made the moment you swallow some coin-seller’s tall tale about their great grandfather’s untouched coin collection. Usually associated with a feeling of lightness in the wallet followed by acute embarrassment when you show off the “original” prize at the next coin club meeting – only to learn the coin has been whizzed.

In the old days they also used this term for clashed die coins which we all know now to be total nonsense.

I have not heard that term used in a long time.

made about as much sense back then as it does now

To learn and to laugh. That's what I get out of this place.
I try to pay attention to the experts.
