I have about 20 1946S cents that on the reverse is the outline of Abe. I tried to take a picture of this...but I can't get the proper angle to get the shot...I'll keep trying. I did look at over 3000 wheats this evening just to see if I can find this in another year or mint. Nothing like the 46S. Is it the metal composition or something else. I will try to get a picture of this. Thanks!  Edited by HoosierDaddy

Sorry...that's as clear as I can get the picture..the outline goes completely to the rim on both sides and lines up perfect with the obverse.

Sounds like a die clash mark:  These happen to the dies after a die strike with no planchet leaving marks on both dies of the area around the devices on the fields of a coin. (The fields are the outsides of the dies, devices are deeper into the die) Here is the postion of the dies when this occurs:   The resulting marks happen on the dies until they are polished to remove these lines.

If this is what you are seeing, it's caused by excessive pressure when the coin was struck, it shows up on some coins after a bit of wear.  I find them every so often searching wheats. |

I have a totally different theory on these. No one else agrees with mine though. I feel this is cause from constant die polishing to remove the clash marks and eventually wears that area of the die making the area raise when coins are struck.

coop wouldn't excessive polishing make these appear on BU coins as well as those coins which have a considerable amount of wear on them?
I have never seen an uncirculated coin that exhibits this ghosting of the obverse.

Just odd...the only ones I got are 1946S. I have thousands of others!

Metalman...your picture is exactly what all of mine looks like...what year is yours...I see it's in a 2x2?

No the polishing removes part of the fields area where the two dies clash together. The polishing would remove more and more of the field and make the field thiner in some spot and normal in the area not polished. Thus I feel we are seeing the areas that thinned the area to make this ghost appear on all coins after the clash was removed.

The coin I posted is also 46-S, I have several in a red box around here some place, I will have to look for them and see if they are all 46-S also, it's been a couple of years since I posted mine here.

The thin, sharp lines are indeed clash marks.
The soft, mushy 'areas' that look like a ghosted abberation of the opposite side are a result of die wear and nothing else. The dies tend to wear faster where the pressure difference is greatest - where the relief changes the most. This would be the outline of the bust.
If this were a case of overpolishing the dies all of them would have thin, nearly missing details in many areas of the design...this is simply not the case in a number of instances I have seen. It's just die wear.

After looking, again, at a bunch of other wheats I found more examples of this from other years and mints. The bunch of 46S ones that I found had made me think that there was a problem with only them.
