You Vs. ICCS: 1951 Silver Dollar

I'll go MS65, I think that the way the image is lighted it is hiding the chatter.
This is my MS 64 coin, slightly rotated.

Guess it depends on your definition of "chatter".

How about "henpecking"?

@thedollarman
Try taking an image of the coin directly above it and without the side lighting and post the image, This way we can more accurately assess the coin.
I am still leaning towards SP65 at this stage, regardless of what ICCS graded the coin at

That is a beauty of a coin!

That's more like it
SP64 is what it is, Your images tended to "Soften" the chatter on the coin and made it look like a 65 .

don't take this as us bagging on you though please, we're an educational forum. a specimen strike is struck with highly polished dies and specially prepared planchets and is handled with lots of care. the amounts of king George VI specimens struck is usually very slim aside from 1937 issues..these coins are hand struck and were often on a made to order basis. they are the closest the mint could get to proof strikes and represent the best of the best that the mint could produce. specimen strikes are always very crisp due to being struck slower and with higher pressure, sometimes they are struck more than once. since specimens were meant to represent the best and were handled with care, they shouldn't have any noticeable surface issues and were never meant to be treated like circulation strikes.

on the other hand, circulation strikes are struck in higher quantities for general commerce and come in contact with each other since they circulate and were stored in bags with each other. taking into account how the different strikes were handled in completely opposite manners, they are 2 different animals when it comes to grading. specimen have to be pretty darn clean since they never came in contact with other coins unless they were mishandled, to make the 64 grade. while an MS-64 can have some contact marks and noticeable minor issues since it began it's life hitting other coins etc. and was not handles with care, so some marks are expected and taken into account since that's how it was meant to be treated since day one. for example, a mint state coin with surface preservation like mine would get a high mint state grade like MS-66 easily since a mint state coin is rarely this clean..meanwhile if trout's coin was a specimen it would be considered mishandled since specimens were never intended to be treated like circulation issues so because of it, that amount of surface preservation would get around an SP-60.

but they are handled differently and that is taken into account, look at your MS-64 compared to my SP-64..there is obviously a much better preservation of the surfaces on mine compared to yours. due to the way they were handled mine has no contact, as expected, while yours has obvious contact. a bag mark or two on an MS-64 silver dollar is expected..on a SP-64 it can't exist to make the 64 grade...so i'll politely disagree my point here is rubbish. I fully agree however that the technical merits are what grades a coin..the merits very by strike though to an extent, mainly in grades with mo wear since with wear an SP-55 is as worn as an AU-55 etc. it's all about surface preservation as you have said BUT the grade determined by surface preservation does depend on the finish of the coin.

This is the PCGS image of my coin and it looks technically pretty much the same as yours.
I think that what you are trying to say is that out of the two coins although they are the same grade The Specimen coin is more desirable.
Now that makes sense to me
