I magically removed corrosion from a large cent.

    First, do NOT try this at home. This is the exception, not the rule. This coin sold for $99 to a fellow collector friend of mine, who told me he bought it on Heritage after he sold it to me, which is how I found the pics. I cracked it and used acetone and a toothpick, mainly just to improve the appearance of the focal areas. The crust came off without a whole lot of effort, save for a couple specks. I thought it was F15 or VF20 on a good day, but I'm just happy it straight graded. I did NOT plan to send it in, but after de-crusting it, I thought it had a shot, amazingly. And it did!

    Before: NGC VF details.

    After: PCGS F12

    This is the S-230, perfect die stage I. No reverse die crack. Price Guide value is $325 in F12. I did not have them add the variety, but some wonderfully astute members here identified it.

    VF was way to high for this coin. F-12 is the most it should grade.

    Nice job on the restoration!

    How did they get it so wrong?

    I'll try to answer this.

    C-B-D did a great job removing the BLACK GUNK from the coin. There are many products you can use to remove it. That is not the reason the coin was "detailed" by NGC. The coin's surface is corroded. It still is. Unfortunately, a majority of old copper is porous.

    As for the grade, IMO, based on the grading guide images, TODAY it is closer to a "commercial" VF 20 than a Fine 12. Decades ago Fine 12 would have been plenty. I suspect the NGC graders pushed it to a VF because once a coin is detailed, the coin's grade matters little. I also suspect the PCGS graders used "Net Grading" to drop the coin to Fine 12.

    :angelic: Just think, everyone would possibly be happy with a F-15 straight grade.

    Great job on restoring that coin. Glad it straight graded. :)

    Yup, sure is. And once corroded it is forever corroded.

    Yup, sure is. However, that is not a reason to straight grade coins that are problem coins, undeserving of a straight grade.

    Not me, never me ! But I understand your point.

    And it is your last line that kind of explains it all. That being that the TPGs are simply giving people what they want, even when the coin is undeserving.

    All of that said, CBD, ya did a good job, hat's off to ya for that ;)

    Very interesting. Who'd have thunk you could remove corrosion - if not from the coin, at least from the label...

    They do that all of the time.

    I noticed the corrosion still present too. I just assumed it was given a pass like cleanings are on bust halves

    First of all I'm not singling you out here, just trying to make a point, and your comment does a good job of illustrating why it needs to be made. Maybe not for you, but for others.

    For example, what is corrosion ? What is the difference between corrosion and corroded, if there even is a difference ? Can corrosion be removed ? Given the comments that a lot of people make on a regular basis I'm not sure that they understand these things.

    I really don't know how to explain it other than this. Corrosion is a physical action, it is the metal decaying, an eating away of the metal, the metal turning from one thing into a completely different thing that is no longer metal at all. And once corrosion begins it is there forever, it cannot ever be removed.

    Think of rust on a piece of steel. The rust itself is not the corrosion, the rust is nothing more than the result of the corrosion. It is a substance that used to be metal but is no longer metal at all. And once a piece of steel begins to rust, the damage caused to that steel is always there and it will never go away. Sure you can remove the rust, but you can never remove the holes, pits, depressions, call it whatever you want, in the steel that were created when the steel corroded.

    The exact same thing happens with coins. Coins corrode, just like all metals, and once they do they are damaged forever.

    What CBD did to this coin is just like removing the rust from a piece of steel. He removed the result of the corrosion, but not the effects of the corrosion. The effects can never be removed.

    PS Should you give CBD a "like?" ;)

    Emphasis on "away" -- something combines with the metal and takes it away from its original position on the coin. And once that happens, it can't be put back, any more than you can un-scramble an egg. You can turn the oxide or sulfide or chloride or carbonate back into metal, but you can't put that metal back where it came from on the coin. (And if you try, you're "doctoring", not "conserving".)

    Sometimes corrosion can be removed by further wear on a coin. The price, of course, is the grade goes down.

    It looks really good! You did a nice job.
    The corrosion really took away from the look of the coin.

    That’s only if you believe the only ones capable of doing what John did are NGC & PCGS. Otherwise, it looks like he conserved a coin and the graders agreed.
