Lem E

Saw the designation and had to have it.

1944-S Lincoln cent, NGC graded MS 66RD:

Regarding @powermad5000's 1891-S Seated quarter, although I can't see much detail from the single photo posted, what I do notice is that the coin appears to be a flat "white" without much frost or "cartwheel", which would suggest that the coin was "dipped", perhaps a little too long or repeatedly. Although the grading services usually don't designate a "dipped" coin "cleaned", obvious "dipping" can lower the numerical grade where the coin appears "washed out", dull, or unnaturally white for a type like this one, whose uncirculated survivors are usually toned.
   Here is an 1879-O Morgan dollar (not the prooflike one I recently posted on the "Post Some of Your Morgan Dollars" topic) that PCGS graded MS 61 some years ago and is housed in a green label holder. The coin doesn't have the number of abrasions one would associate with a Morgan dollar in that grade and has some "cartwheel" but is unusually light in color.

Nice color on that one. 

That’s a shame. You would think it would be pretty obvious why it got a 61. Still looks like a nice piece no matter what the grade is. 

I'm really not totally sure @Lem E as the reverse looks just as good. It is sitting in my SDB so I can't currently access it right now, but maybe I will revisit it again in the future and take another look. I remember sending it in and I know I didn't expect a 65 but I really though it was a solid 63 and maybe a 64. I do remember there wasn't a lot of chatter on it so maybe the graders didn't think it was fully struck??
It is one of my favorite coins though and looks great!

I really thought that this beautiful coin would have graded higher when I bought it raw.

Must have erased the photo of the raw coin, just use your imagination for it. #5

Not quite right....
Die Variety = Varieties always occur on the die itself. The are anomalies of one kind of another on the die (outside the "norm" for that die's design, etc.).  By this definition, coins that are often called "errors" are actually varieties (1955 DDO Cent, 1937 3-Legged Buffalo Nickel, 1804 Spiked Chin Half Cent).  A die variety is also the unique combination of obverse and reverse dies.  Die varieties occur on multiple consecutively minted coins in a series.
Die State = are a measurement of die deterioration based on evidence left on a struck coin/token.  This would include die cracks, cuds, clashes etc.  Die states occur on multiple consecutively minted coins in a series, and generally progress over time. 
Errors = These are "one-offs" and do not include anomalies on the die.  Errors occur when there is a mechanical defect in the striking of the coin (off strikes, double strikes, wrong planchets, mules, etc.)

Now cracked out and in the Dansco.
