So much for quality control at the mint. Maybe a pocket job?

Would a planchet be thin enough to allow a partial image of the eagle to be printed?

All that coin needs is the smaller coin that is the mate to that strike. If you have both, the prices can go LOTS higher. I saw this 1973-S Proof Ike mated with a cent on Heritage. http://coins.ha.com/c/item.zx?saleN...4&lotNo=3523That mated pair sold for $40,250. back in 2008.

Wow! Two very cool errors. I agree, you really do have to wonder how these get through quality control haha.

It appears that the design transfer happens thought another planchet:  So it can happen. But the neater error is to find both pieces. |

This is another one of those errors, that if you're looking for them, they'll show up. They are rare and highly valued, so when they come to market, you know about it. It seems that this type of error is more common with Ike dollars too, although it can be found on multiple denominations. The example in this auction is not of the highest quality either. It should not have been graded by ngc. Those scratches are just terrible. And a note on quality control: The appearance of one major error does not signify terrible quality control. Things of this nature happen, even with the strictest standards. It is not to say that there aren't holes in the system, though, as evidenced by the missing edge lettering dollar scandal a couple of years ago. |

I'm going to bookmark this thread in hopes that maybe Mike Diamond can explain this as I scratch my head  (I have quite a few USA & World errors and have some with the design under the indent that I may need to re-examine after Mr. Diamond explains how this was done) |

While I don't have this coin any longer, it was one of my favorites.  I studied it and realized the image of the monument you can see on the obverse didn't come from another coin, it's the reverse of this coin showing through the coin was hit outside the collar with so much pressure. Mr. Diamond saw it and said that the strike pressure was set very high or the gap between the dies was set very tight. Either way, it caused the coin to spread to the size of a half dollar at it's widest point and with all of the metal pushed away from the center, it was so thin that the reverse die pushed the metal through so the Lincoln Monument image could be seen on the obverse through the flattened image of Lincoln. How did this coin make it out of the mint, and if it made it out, did it's mate make it out or was it destroyed? I sold the coin on ebay last year, but I sure wish I had the second coin that was caught in the strike, I would have had both graded and sold the pair for far more.

Are proof coins of this era multi struck? If so, I would think that the detail's coming through is a combination of many factors. First, the copper planchet is small and weighs much less than a cent planchet. This means that it is more than likely a little bit thinner as well, allowing a lightly detailed figure to show through (similar to a shallow strike through of any other kind). And if the proofs are double struck, the copper planchet could have been struck into the dollar planchet, got struck and was struck again allowing more of the design to come through to fill the high relief of the ike design.
edit: If the proofs were double struck, the copper planchet could have been struck into the dollar planchet,got stuck(retained in the dollar planchet) and was struck again allowing more of the design to come through to fill the high relief of the ike design.

They are struck multiple times. I feel your assessment is correct.

I still remember that cent struck into the 73-S proof--amazing error!  |

That planchet wasn't intended for an American one cent!  |
