Found this one in a roll. Looks like it has a little woodgrain effect going on. I thought the woodgrain issue plagued only the early years of the Lincoln Cent. Is this common for the later years? You think it's worth saving or just dump it into the copper penny jar? I played with the lighting a little bit to bring out the woodgrain.     |

I just found a wood grained 1981 LMC and had the same exact questions. |

I have noticed it quite a bit on 1979-1982. I have also noticed that a lot of the woody cents have problems like corrosion and verdigris so I keep the better ones I find.

just thought i'd say it looks like perhaps the surface only of the planchet was culpret here ie.having the 'graining'ie. in this case grooves / or highs ~N lows, pre-strike.not as in the earlier planchets having 'improper' alloy mix that resulted in the 'woody's'.i might keep it , myself as a 'discussion piece.'

About $10.00 in rolls later and I can see that these are very common! So...into the copper jar it goes!

I've kept all the nice looking woodies that I've found. I have about 35, and 90% of them are from 1980 or 1981. I keep them in an old penny folder.
Your pictures are nice. I have a tough time taking pictures of the woodgrain cents for some reason.
Also, the grain pattern of the '80s and '81s is different than the grain pattern of older cents. The stripes are a lot narrower.

I posted this on another forum: Quote:
find these most often from 1980-1981, they are fairly common. Normally they only have the graining on one side, but some have it on both sides. At some point I want to bring one into the lab and analyze it on the SEM-EDXRF to determine the composition differences. However, for now I've postulated a theory.
I don't believe this is not caused by an improper alloy mix like the 1920's Lincolns were well-known for. I believe some sort of material is embedded into the planchet as they are rolled. This material is likely the rolling fluid mixed with metal fines. If only one roller is contaminated, the feature will only appear on one side. To support my theory.....if it was improperly mixed alloy, the feature should appear on BOTH sides consistently....but it does not.
We've discussed this on the CT forum a good bit. I sent one to Doug on there and he dipped half of the coin to see what would happen. Most of the lines were removed, but I could still see some faint traces. He has been retoning the coin in a window sill for a few weeks now to see if the lines reappear.....if they do, that would support the idea that the lines are strongly embedded into the metal. If not, that would seem to support the idea that these happen somehow post-mint.
If anyone else has any insight to the modern "woody", I'd love to hear it.
I only save these when they are strongly grained on both sides and in decent condition. They seem to be so prevalent in 1980-1981. Lincoln Cent Lover!VERDI-CARE™ INVENTOR https://verdi.care/

Oh....personally I'd keep that one. It has nice graining on both sides. I toss those in a coin tube. I'd put a drop of VC on the reverse and rub out that residue with a toothpick before storage.

I have to agree with the roller theory because I have noticed that the lines on all the LMCs I have seen are very fine, parallel, and rotated from coin to coin. The LWC woodies usually have obvious alloy issues with lighter brassy streaks mixed into darker bronze or you might find a gem with bronze streaks mixed into brassy yellow    |
