<p>[QUOTE=&quot;John Burgess, post: 4960213, member: 105098&quot;]You been here longer than I have and know clearly more than I do about coins, I&#039;m by no means a professional or authority on any of the subjects I discuss. In fact I take you as an authority <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie8" alt=":D" unselectable="on" unselectable="on" /></p><p>Striations like in the first photo could be thought of as woodies but they certainly arent. I&#039;ve seen striations and woody on the same coin, the toning is stripped in the same direction as the striations. Striations are lines left on the planchet from rolling or &quot;roller lines&quot;. The have no effect on the toning anymore than the difference in height between fields and devices because the alloy there is the same composition so it doesn&#039;t tone at different rates.</p><p><br /></p><p>the buffalo could be improperly mixed alloy since they are 75% copper 25% nickel although I&#039;d have to suspect annealing as the culprit of this type of toning on nickels, as it usually is. And I can&#039;t rule out evironment either on the buffalo.</p><p><br /></p><p>People think of toning as a surface condition, which it is, but in the case of the woody cent the &quot;wood grain&quot; appearance is in the metal of the coin toning at different rates. You could remove the toning but it will retone in the same stripy way over and over.[/QUOTE]</p><p><br /></p>
