Anyone Wood Grain Toning Collectors? - Post Yours!

Twins! Well almost. These two came out back to back from a roll of 1939's.

One of my favorites.

Agreed. Beautiful!

I do like that 1920

I don't think that's a woody, but it appears to have the black parallel stripes present on many cents of the late 70s and early 80s. I believe Coop has some information on these.

That's the right attitude.
The wood grain pattern occurs when the alloy (0.95 Cu, 0.05 Sn & Zn) isn't mixed properly, so some areas of the metal have higher tin or zinc content and thus a lighter color. When the ingot is rolled into a sheet, it is stretched out laterally, as are these patches of brass or bronze, creating the 'woody' pattern with light-colored streaks.
Although your coin is similar, you can see that rather than the yellowish stripes present on other woodies, it has very fine, parallel dark lines. There have been discussions about this on CCF before, so maybe Jbuck can use his superpowers to locate some of those threads.

Good to see some additions to this thread.

I don't think that I have showed this one in this thread;
