Real grade, AU-58. There is a rub on Ms. Liberty’s right knee. Holder grade, MS-62. The head is probably full, but it is slightly impaired from a touch of wear.
I can't yet distinguish high-point rub from not-quite-fully-struck, at least not from photos. The way this is glittering with luster, though, I wouldn't be a bit surprised at an MS grade.
I would say an AU-55 or AU-58, which I find preferable to anything below MS63. However, I don't collect these quarters. Never have.
I'm seeing about an AU 55 beautiful but to many lil bag dings for MS hair and face might even be defined enough for FH but seems just just shy to me
Compare the coin on the left with the picture of OP coin on the right. Look at Ms. Liberty's knee and c
That one on the left is as fully struck as I've ever seen an SLQ. Wow! Sure, I can see the flat area on Liberty's knee. I just can't tell from the photo how much of it is rub, how much of it is strike weakness, and how much of it is just toning variation. At least, not yet, I can't.
First reaction was 58, does look like just the sort of coin that would be in a 62 holder as the wear is very minimal. Pretty coin
The one on the left is a 1917 Type 1. Almost all of those coins are well struck. After that success, Herman McNeil decided the mess with the design, which made it harder to strike and doomed it to an early retirement. Roger Burdette said it was because he wanted to dress Miss Liberty in armor in preparation for World War I. Here are the other two types. Both of these coins have the "Full Head" designation. The date was vulnerable to wear on this type. The mint also sometimes did a poor job at striking it. The date was placed in a more recessed area starting in 1925 where it bared up better in circulation. These coins were also well struck more often. Both of these coins are in MS-65, Full Struck holders.
I'm throwing my hat in the ring at MS63 FH, maybe higher. It could be my eyes, but I'm just not seeing the wear to bring it down that others are pointing out. Please don't wait too long to reveal.
