I have seen many cents with roller lines in them but this one takes the cake. This 1946 P LWC shows this stripping on the obverse and reverse as well. You can even see the lines going through the devices. I can just imagine what this cent looked like when it was first minted and I bet it was amazing.
Those are roller lines. Wood grained looking coins, "Woody's",come from improper alloy mixes. I have several of those. One other tell tale of roller lines is wherever the coin has the greatest wear, normally the high points, the roller lines disappear. On a woody, they don't.
