Hey B, after further review the roller is the culprit, I was wrong. The rollers that are referenced here are the rollers that pull the planchet material into the planchet punch, the rollers might have something on them and they impart this to the planchet in a random application before it is Die Punched.

The woody on the other hand is caused by a poor alloying of the copper, tin and zinc. Some of the best ones are from right after ww2 when brass shell cases were incorporated in the cent alloy> In researching this I found Beee utiful cents with the yellow brass color and the red copper, just soooo cool.

Here is a video of how a quarter is made and you can see the the planchet material being pulled off of the roll by the punch feed rollers.



Here is the real woody
