Someone posted this as a split obverse die...

I'm certainly no error expert but my first thought was a struck through die cap with some kind of wire holding it on or something.

Ohhhh I have a feeling I'm going to be so wrong about this lol.

Anyway...it was just posted on reddit in r/coincollecting

That lower portion is awfully straight and uniform for a die crack

Struck thru a split die cap.

MsMorrisine

I’m surprised the split isn’t more ragged…

Talk about a nail through the head.

I saw that in one of the Facebook groups, I linked him here for its near twin.

Very worn die with a large crack/split. The cuds on coin pic appears to be the same obverse die

Very interesting.

Would like to see better pictures before I could be sure, but my first impression was a very late strike from a cap that got jammed into the crack in a split die.

MsMorrisine

Very interesting stuff

MedalCollector

It’s a spit die (or at least two large radial die cracks). AND it was struck through a die cap.

These are very common and I’m surprised by the variety of different answers provided here.

Interesting.
Thanks for sharing.

Nice dime error... The above explanations (cap, split die) seem to explain it....Interesting to see two examples... Cheers, RickO

This is exactly how I would describe it, it wouldn't surprise me if the die cap was what held the die together long enough to allow it to strike the OP's coin.
