Die crack on observe from rim to rim
First, this is a US coin and belongs in the US coins forum, not the World and Ancients forum (I have requested it be moved).
Second, a die crack on a coin doesn't "look like a crack". It looks like an anti-crack, a raised line. This line "looks like a crack" and isn't raised, so it's not a die crack.
Given that it's an early Zincoln, I'd assume it's some kind of flaw with the plating.
In this case, designation is only used for "major" planchet flaws. This coin has minor flaw , therefore do you agree that the coin has no value.
@acadien .... The term is 'obverse' not 'observe'.... might be a typo, but wanted to make sure you knew. I agree with minor flaw. Small or no numismatic premium. Cheers, RickO

It’s not a die crack- it’s a scratch from rim to rim –
Looks like a cracked planchet to me
Planchet defect would or could be legitime. On the other hand, the answers coming from above come from people who actually master the mistakes much more than me. Thank you all, stay healthy.
