I'm just posting these pictures of a 49-D Lincoln I found in a roll search, with what I believe is a valid die clash error. I wanted to see how they viewed on CT. Getting the light and focus correct is always a challenge. Any opinions, suggestions or comments on the photos or error are always welcome.
@TJ1952 I don't see a clash. I do see some deformation on the reverse, but it's hard to tell what it is when the dang picture is upside down. Chris
Okay, educate me again. I thought a die clash example is when the image (Lincoln's profile) on the obverse of a coin, comes thru or is visible on the reverse of the coin. The deformation you see on the reverse is Lincoln's profile. The reverse of this coin is upside down but he's profile is right side up.

No! A clash occurs when there is no planchet in the coining chamber, and some of the image from one die is transferred to the opposite die. When the next planchet is struck, the impressed image becomes visible on the coin. Chris
Okay, thanks! So what I have as indicated by @Evan8's attached link is Progressive Indirect Design Transfer (PIDT) or Internal Metal Displacement Phenomenon (IMDP), better known as ghosting. P.S. How did you like the pictures?
It isn't an error. It is an effect often seen on very late die states. The technical name for it is as you mentioned above, but it is known in slang as "ghosting."
Okay, so even though it's listed in this link (http://www.error-ref.com/?s=ghost+lincoln) it's still not technically an error. It's a form of die deterioration. Is that correct?
