1911 - Fine to Fine+
1915 - VG, aVG not bad pair and real.
I suspect 1911 is likely cleaned.
Otto - bear in mind Sel_69 and I grade according to British scale which means American VF is more British Fine. The VF25 piece you show is bare Fine in our money and the EF45 is bare VF.
A way I grade
VG = Full band across George, middle can be almost indistinct
Fine - Division between band and jewels must be visible, middle diamond blended with detail
VFine - the Middle diamond must be distinct from either band, and the two sets of pearls may be blended but distinct from bands
EF - The pearls either side of middle diamond must be sharp and garter belt on King's chest must be sharp.
