    I don't think you grasp it Jazz.

    When a coin is annealed it is sent through a furnace. This softens the planchets so that it isn't quite so hard, making striking easier. All modern coinage is annealed... and there aren't usually problems. From what I gather (and experts please correct me if I am wrong) Improperly annealed coins are basically burnt...or spent too much time in the furnace.. causing the discoloration of the planchet. Other then that the struck coins look normal from what I can gather.

    i perfectly understand the concept of theses errors that is correct the coin stays in the furnace if you want to call it tha,but i never heard the term burnt before ,and i think it has to do with the chemical break down in the annealing process with in the metal when the coin stays in to long just my theory

    I thing that;s why there are different colors improperly annealed planchets. there ;s no specific conclusion how these are made nobody really knows yet.

    You shouldn't make assumptions like that. You have no idea what my knowledge of this is. I just might be in a profession that uses metals regualrily and am therefore required to understand the properties of many types of metals including copper and nickel.

    It's true that these coins come in varying colors...your coin however is changed in color due to being buried IMHO. I'd need the coin in hand to be sure...but it looks very much like a coin that has spent time in the soil. Take it to a coin dealer and see what they tell you and how much they offer you.

    This is correct. The process of annealing has to do with reorganization of the metal molecules. It is commonly used to reduce strain in metals to make them less likely to fracture. In most applications, metal is cold worked and as a result it's molecular structure gets strained. You will find that when you flex metal it becomes harder to flex before it fractures because the metal is having dislocations pile up in it. Annealing occurs in 3 phases. The first is reorganization which simply provides enough energy for the molecules to move a little bit and slightly reduce strain. The second phase in recrystallization in which the molecules actually being to realign a bit and reorganize their crystalline structure. This is where most annealing stops because proceeding farther drastically alters the properties of the metal. The third step is grain growth.

    The metal becomes more maliable during this process because these dislocations (which cause fractures if they pile up enough) are reduced.

    i have taken it to a dealer akready as i stated in my previous post and said it was a improperly annealed planchet I didn;t ask him how much it was worth but he said ir;s a very interesting piece with greyish fields (the pics don't do to much for the color of the coin )and he said no way this is a dug up coin . I will bring it back to him to see how much he would pay me Thank you for your input everybody.

    Well, we have just expressed our opinions here based on the pictures. It could very well be Improperly Annealed. Based on the pics, I feel it's not...but to be honest, the pics aren't really good enough to give much feedback on the coin. With better images, the responses may be different.

    I hate to tell you that;s not dirt it may look like that from the pics but dirt ins;t that color and it;s not corrosion it is nickel flaking off of the coin you can;t tell by these pic / That is a very bad interpertation of dirt I hope my diagram is not to complex for you copper washed Here;s a dug up cent now doe;s mine look anything like that come on man I just don;t understand this is an annealed brand in my hand. Thanks for everybodys input on my improperly annealed planchet coin soon to be slabbed.

    dirt would flake off too...

    you mean soon to be body bagged... but then the grading company would have no idea what they were talking about according to you

    What you are kidding me i hope,don't tyou think that dirt will cake up it doesn't flake now you are saying to me that dirt peels off what I had it The coin will be body slabbed and i will be glad and you will be sad End of thread.

    There is one other thing Matt. Since the mint produces more cents by far than any other coin, the annealing furnace often accumulates large amounts of copper dust. It is the settling of this copper dust on other coinage planchets during their annealing process that causes what they call an improperly annealed planchet or a copper washed planchet. It is the copper dust that causes the discoloration. Sometimes it will be blackish in color and other times copper colored. But without the copper dust, no annealing error occurs.

    ok, so WHEN this coin comes back in a body bag... will you admit you are wrong... again?

    Jazz your problem is that you are always right... if someone has something to say that you don't agree with... they are wrong...

    I will be the first to admit that I have been wrong many times... and ill be wrong many times in the future im sure.

    I speak here from experience, I buy tens of thousands of coins a year. I have seen a lot of weird stuff... On the weird scale... this is about a 2 as it is something we see a lot... ask any dealer worth their salt... they will tell you that this is a ground find.

    Your full of hot air... You wont send it off, if you do any they body bag it... you wont bother to update anyone... lets just wait and see

    aahh, I see... so its not necessarily a burnt coin... just a foreign substance ends up on the coin while its being annealed and then basically cooked to the surfiace. Thanks for the clarification. :)

    Yes we have to wait and see i agree, but i'm not full of hot air maybe cold air but not hot air

    My planet can go down to a degree of 100 below your zero level but we have meltselenters to capture the cold air and transform it to a temperture of were our inkrissent bodys could with stand the level of tolerance. .

    oh the coin When the coin comes back i will let you know and if i;m wrong i will admit that that's no problem with me.i may have to leave earth to go back to my planet ZECTAS for awhile but I will be back.

    I told you a couple of times i brang it to a error dealer in my area awhile back he said it was a sintered planchet how many times do i have to explain that please read the whole thread
    ALIEN ZEC please call me zec not jazz you could call me Zec jazzy or Jazzy Zec or i prefer Jazec Please

    There's a difference on how a material reacts to being in the ground. You have shown us two different examples of how they react. It's obvious there is a difference.

    which error dealer did you "brang" it to?

    Digenes Just a collector

    And when my die clashed nickel comes back from PCGS slabbed are you also going to admit you were wrong or will you still insist that PCGS is also wrong? Oh it is at PCGS as we speak, submisstion number 3987189

    Looks like nickels that go through the laundry in a pants pocket to me.
