It is much easier to condemn as a fake from an image.</p><p><br /></p><p>Grading: Good image, circulated coins Yes. MS coins No. You can't tip/rotate the coin to let the light plat over the high points checking for very slight wear. So if you can't guarantee is is MS you can't guarantee any given MS grade.
