Highest Grade From Rolls

How do you grade a new coin based on market grading?

Don't quite get what you are asking nor your motive here.
But whatever.. I grade coins just like everyone else does; and that is by looking at them.

 

I agree with everything but the MS 67. And let me explain why. 69,68 and 67s have to have incredible strikes, highly unlikely for busiess strikes found in random rolls. Up to 66 the strikes in the grading are balanced in the market grading system. Coins known to have weak strikes are discounted for that likelihood, such as the case in New Orleans Morgans. Once you get about 67 though, whether written in the standards or not, graders start putting significant emphasis on the strike quality, AND, it has to be visibly at first close look without any hits. If you tilt it in the light you might see a hit, or look closely at a letter their might be a scratch, but from general appearance it should look perfect, and that is very low probability with normal handling, especially with soft metals.

Might you find a 67,68, or 69 in a roll. As you point out, they have to come from somewhere and there is some theoretical statistical odds that you can measure. But that is a quantum leap in odds from a 66 and down, and that is the essence of his question. What is the best he can expect to find in a roll, which assumes there is some reasonable limit on his time and patiences
then I'd still say a 65, MAYBE a 66 if he's very lucky. If he finds a 67 in a years worth of looking, man, he should play the lottery.

Odds on any random roll? Good luck finding a 63...

I agree , I collected wheaties as a kid , but grew away from them , most of them were VG-F , not until buying a really nice '43 for my type set that I noticed the beauty of the series .

eh...I actually like the memorial better. If the Obverse was as sharp as the Memorial, the coin would be better. Right now I'd be happy to see all the politicians off all the coins...PERIOD

Get some art on those things.

Now it is my turn to ask. Where did you get your numbers, Doug. Per PCGS on Heritage, there are a total of 53 MS67 2005 cents with only 5 higher (not satin). NGC is either 0 for both or not listing their numbers.

 

Somewhat skewed? Who is sending in a coin unless they think it is an MS70?

Doug, I'm a bit confused. I'm not sure what the second point your making. Your normally clearer that that. If your saying that I said every single MS69 coin came from a bag or a role, I was just repeating that you said and take your word for it.

In any event, 111 MS69 out of 10,000,000,000 coins is still looong odds

I understand that. Those were for 10/07/08. They do not change that fast. It is like they are talking two entirely different items populations - or they made a mistake at NGC. Look at the 2006 & 07 numbers;
.........66 67 68 69
2006 . 16 09 02 04
2007 . 83 10 02 00
They look more like they fall into line with what I found. I will bet that the 111 is a typo.

 

I found quite a few MS 65's MS 66's and one MS 67 in a roll of 1939 S lincolns.

 

I saw them. I did not say you miscopied them. But somehow they just do not fall into line with the others. Even the "D" mints don't jive that year with the following years. I don't know what it means, but the 111 just seems fishy to me.

 

So did I!

 

So did I add up the numbers and found 111 to fit with their total.
