I'm not sure if these are error coins or... Could someone tell me what these lines are. They are on both sides. I have more than this one but this is really the only one you can see from a pic. Hopefully even now you can see it. IDK why it's so hard to take these right...
Could be where the alloy didn't mix quite right, commonly known as a "woodie" for the wood grain appearance.
Yes to improper alloy mix - I want to share this webpage with you - http://www.error-ref.com/improper-alloy-mix/
Welcome to CT Kevan!! I have found ALOT of 1980-1981 LMC's like this. They seem to be very common for these years. I don't keep them unless they are very bold lines on both sides.
