1918 Lincoln Cent . Lam ?

Possibly a die crack?

looks like a lam to me.

Definitely a Lamination issue.

. If you have searched, any time at all, especially wheats, you will find that lams will amost always be paired with woodies but not always the reverse, the woodies need to have a bad enough alloy mix to create the lam and that does not always happen. So, when you have a lam, there will almost always be a woody present, but you can have a wood grain coin without a lam.... For the woody fans, scroll down to the very bottom and read, it's not spelled out that way but that's how it is.
