And, in fact, you see the same orientation (parallel to the coin&#039;s edge) at the <i>left</i> end of the arrows, far from the crack. I assume the lines just build up that way as metal flows toward those areas of higher relief.</p><p><br /></p><p>Thanks for sharing the coin, and thanks for these superb photos![/QUOTE]</p><p><br /></p>
