How does strike doubling affect grading process?

[duece2seven]

Going through a bunch of 69-S BU rolls and conducting my own little case study as I go. Just curious how strike doubles grade out? I know strike affects grade but never heard this discussed in detail. It's amazing to me how some of the most beautiful coins seem to exhibit this trait. Then again, the alphabet still amazes a simple mind like mine!

Strike starts to matter more in the highest grades.
For the average 69-S cent it probably does not matter.

We have an alphabet??? If it is part of the striking process which strike doubling is I would think that would not affect the grade... Then again I am no grader!!!

Sorry to disagree with you Jfines but...

Strike doubling is not "part" of the striking process...
..A coin is struck when the 2 dies travel together and STOP!
..it is the moment of impact to the last space between the 2 dies are at their least distance from each other that a coin is struck
..When the dies reverse direction so that the coin can be ejected the coin has already been struck.
..Anything that happens after this nano second time frame (The Stop) is considered damage
..whether it happens at the mint or after it leaves the mint

..Strike doubling is when the die is not tightened all the way down and bounces so that the die touches the coin after being struck.
..this is considered damage as it happens after the strike.

..Strike doubling would effect the grade as it is not a perfect coin or the representation of a perfect coin BUT by how much?
.. if the coin without SD would grade MS 62 the SD would not matter or really change the grade...
.. if the coin without SD would grade MS 68+ then.. Yea the SD may take it down... MS 70 could never be a possibility with a SD coin.

here's a 1913 buffalo nickel i have with md on the obverse--a couple of dealers i showed it to said it had no extra premium--

Good thing I am not a grader... Thanks!!!

This is one of those question where I would like to see an example. Most cases of MD should be mild enough that I wouldn't expect it to be factored in. If someone could show examples for or against that might be helpful.

I just got off the phone with Independent Coin Graders. I talked with "Skip" Fazzari who is a very well known grader concerning machine doubling and we both feel that since machine doubling is a function that occurs in the coin press, it should not affect the grade of the coin, even an MS 70 coin. "Skip" stated that he had seen some silver eagles with machine doubling and they seemed not to have a lower grade because of that anomaly type.

I don't think it has an effect on the grade. However, I was a bit surprised by BJ's post, I've always suspected it might affect the grade in 67-70 coins depending on the graders.

Gonna post some pics when I finish this $100/face of 69-S. These won't be graded but they should make for excellent discussion material as they cover the entire spectrum of MD/deterioration/ etc. including some RPMs that also exhibit all of the above! One thing Im most curious about is how much better the reverse is struck compared to the woeful obverse strikes? Its strange.

I have a 1991 Lincoln That was part f a Mint set sent into CC several years ago. In fact he was still in Missouri. I was told to get this graded even though it has a really nice MD on Liberty and the date that it would or should grade a 68. Not only from there but a local Dealer confirmed this even offered to purchase it. So long story short it is in a holder still awaiting to be sent. If I come across it I will post along with the notes passed on to me. Will have to be a latter time though.

This makes me wonder why PCGS has never given a singe MS-70 grade to a wheat cent.

Is it that the planchets were never perfect enough or the strike never good enough or every coin ever made got a mark that was enough to drop it a grade or 2?
Or is it that since they had never given one they were afraid to ever give any because those coins would be so expensive that warrantying them is a big risk?
