Hi guys, I have this 1986 D Jefferson nickel and would like to know if this is an improper alloy mix, woody? I see the lines on both the Obverse and Reverse.    |

It does not look like a woody to me, lets wait for the pros to chime in. John1  |

Am I mis-remembering, or does it seem like roller lines seem to occur mostly on copper cents? Maybe that is just because of this coin being what most folks are posting here regardless of the specific issue.

Question... Can you feel a slight texture to the linear features (on the reverse) if you run a finger tip across them at 90 degrees, or if you gently run a toothpick across them? The reverse photo seems to suggest some texture/relief.

Feeder finger/roller damage can occur on any denomination of modern coins. I am inclined to believe that this is a result of such regarding the op's coin. Woody's will only occur on copper Cents due to the composition of the alloys present in bronze Cents.

I agree with Bumpkin, "Woodies" only occur in copper cents. All (US) coins are subject to possible feeder damage considering how coins are produced.  |

the anomaly appears to not affect IGWT but does Tom's nose, which makes me think Feeder Finger Damage, but I've never seen FF damage that looks like this on a nickel, interesting one |

Correct me if I am thinking wrong: Woodies are what we refer to as an alloy mixing error on copper cents, but it is really an alloy mixing error that could have happened on a nickel. If on a nickel, we just would not call it a woody, but an alloy mixing error? John1 |

I'd expect evidence of poor alloy mixing could appear on any coin that consists of more than one metal, as most coins do, including the nickel. For some reason we see the effects on LWCs more than on other coins. I can't recall seeing a nickel with a woody effect, and I've looked at many nickels, but obviously that doesn't mean it can't happen.

I'd say roller lines most likely, however with the amount of wear, I can't rule out it being some form of intentional damage either and done well after the strike.
if improper alloy mix, it would show streaking or blob like inclusions of pure copper, pure manganese, or pure nickel, as the nickel coin is a Cupro-nickel alloy. it happens, but this isn't what it would look like.
the "woodie" cents do what they do because it's a short distance between brass and bronze and copper, and hard to tell on the fresh alloy but they all tone at different rates. Nickels are CuNi alloy, if alloyed correctly its all melted and blended and uniform. If improperly alloyed, it usually manifests as "blotches" of inclusions of pure metal that didn't blend instead of different toning speed streaks like the cent does.

There are e few "woody" nickels from the 35% silver ones, isn't there?. John1 |
