<p>[QUOTE=&quot;Conder101, post: 2023319, member: 66&quot;]When the alloy was prepared the copper and nickel were not homogeneously mixed so some areas in the ingot were high in nickel content and some were low.&nbsp; When the ingot got rolled out these high and low area got stretched out into streaks in the strip (initially the strip may have visually looked perfectly normal).&nbsp; The strip was blanked, the blanks turned into planchets and the planchets into coins.&nbsp; But over time these streaks of different alloy content toned at different rates taking on the streaked or &quot;woodgrained&quot; appearance as on your coin.[/QUOTE]</p><p><br /></p>
