Just looked at the quarters in my pocket:

1967, milling gone, slightly worn faces with a few nicks, looks silvery
1993, milling good, faces with a nick or two, looks silvery
2000, milling worn, faces good, looks silvery (back NH shows Old Man of the Mountain, which in real life has since collapsed)
2002, milling good, faces good with scratches, looks silvery
2004, milling good, faces scratched, looks silvery
2006, milling good, faces good, hardly any silver appearance, looks really coppery
