What Would You Grade These Lincoln Cents

Hey Zachery,
I'll take a shot (or, rather, 5 shots!).

1948-S: AU-55 details, with some unfortunate damage on the reverse.

1957: MS-64 RB. Beautiful toning which I hope is natural. I've been fooled by artificial toning before. This color doesn't strike me as AT but I'll be interested in what other graders might say about it.

1949-D: AU-58 BN.

1944: MS-62 RB. There is something odd about the grains on the right-side wheat stalk and some letters in E Pluribus Unum are poorly formed. Maybe this reverse was struck from an excessively worn die?

1948-D: EF-40.

Those are my first impressions, and I'm sticking to them!
