This one isn't a die clash but does yours look like this? http://www.ebay.com/itm/1930-S-Linc...190808?hash=item3ac51e2718:g:HF0AAOSwvgdW33IG
Besides that, I've got him beat! Progressive Indirect Design Transfer: A form of die deterioration that manifests itself in the form of a “ghostly” image of a design element on the opposite side of a coin. The force of a die strike travels through the planchet and into the opposite die. After hundreds of thousands of strikes, the outline of the designs begin to transfer to the opposing die and show on the coins that are struck. In the case of Lincoln cents, it is common to see a ghostly outline of Lincoln’s bust on the reverse of wheat cents that are struck in later die states. It is especially visible on uncirculated coinage. This should not be confused with a die clash or a “greasy ghost.” photo courtesy of forum member TJ1952. Courtesy of Lincoln Cent Forum.
Sorry guys, I was out of town for awhile and forgot to come back here. I'm attaching a couple photos. I have my suspicions of how this coin came to be in this condition after looking it over closer, but another collector thought it was worth something so I thought I'd ask.
That is not a die clash, but a squeeze job. Someone put 2 coins in a vice and squeezed. It is worth ~3¢ in copper.
