I agree it looks more like a lamination, but it also could be a split planchet hinge. You'll need to remove the coin and look at the rim to see if it's at all split.
A lamination and be a "peeled" planchet or a defective planchet, whereas a die crack or die break is a crack or flaw in the die that strikes the planchet. A die crack will show as a raised line on the coin, but a lamination will show peeling and or a flaking jagged line or area on the coin. And it's hard to tell for sure from the photos, but the line on this coin looks jagged to me.
