tropicalbats Pillar of the Community United States 6116 Posts	Posted 05/19/2018 8:56 pm I found this coin a while back and finally got a chance to image it. It is quite similar to another coin I have that Mike Diamond diagnosed for me and so I am pretty sure I've got the error correct here. Essentially a bit of hard debris gets struck between the dies with no planchet in there, creating large die dents on both the obverse and reverse dies. In this case, two bits of debris. All the marks are raised, on both sides, and match up perfectly. The one near the date/AM is very much pyrmidic with incised thin cracks running down the edges of the raised pyramid. Pretty neat looking error coin, and rare, but rather a minor error nonetheless. Report this Post to the Staff

coop Bedrock of the Community United States 62064 Posts	Posted 05/19/2018 9:15 pm That looks more like to me that the metal was squeezed on ones side, leaving an indented area and the other side pressing it outwards? PDS If that is the case. Pressed hard enough to make an indent, but not enough to split the plating. Report this Post to the Staff

Errers and Varietys Bedrock of the Community United States 74732 Posts	Posted 05/19/2018 9:52 pm Very nice find! I respectfully disagree with Coop. This isn't Post Strike Damage. Clearly, something hard got stuck in the die and caused some die dents. The debris ended up damaging both of the dies. Errers and Varietys. Report this Post to the Staff

Coppergold Pillar of the Community United States 939 Posts	Posted 05/20/2018 12:36 am I would ask mike diamond or Fred Weinberg what that is Report this Post to the Staff
Errers and Varietys Bedrock of the Community United States 74732 Posts	Posted 05/20/2018 12:47 am Coppergold, don't worry. He already had Mike Diamond diagnose his coin. Definitely a very interesting piece. :-) Errers and Varietys. Report this Post to the Staff
mikediamond Pillar of the Community United States 2738 Posts	Posted 05/20/2018 5:00 pm This coin was correctly diagnosed at the beginning of this thread. Complementary die dents on both faces. A very nice find. Error coin writer and researcher. Report this Post to the Staff
tropicalbats Pillar of the Community United States 6116 Posts	Posted 05/20/2018 9:02 pm Thanks Mike! I am still mostly a varieties guy but slowly getting the hang of the errors. Your time to take a look at this one is much appreciated. Report this Post to the Staff

tropicalbats Pillar of the Community United States 6116 Posts	Posted 05/21/2018 08:04 am This is the original coin where I learned about this kind of error. May as well get all these in one thread. Report this Post to the Staff

Errers and Varietys Bedrock of the Community United States 74732 Posts	Posted 05/21/2018 2:00 pm NewMember, no, it's not a DDR. It's an error coin with severe Die Dents that damaged the dies. You can see the die cracked on impact from striking something hard. Errers and Varietys. Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 05/21/2018 2:35 pm So basically what is being said, it that a die chipped off small areas on the die during a strike, that leaves raised areas on the coins on one side where it chipped off, from the chipped off side, it stuck to the other die. So you see a slight incuse area where the metal transferred to the other die? Report this Post to the Staff
tropicalbats Pillar of the Community United States 6116 Posts	Posted 05/21/2018 2:57 pm Not quite. There is nothing at all incuse involved here. Something, let's say a BB, gets struck between two dies leaving both dies dented. All further coins come out with complimentary, raised, die dents on both sides. Report this Post to the Staff
