They are both die chips. I'm not sure what people are seeing that make it so much "nicer" than the other...they are basically the same thing.
The lines on the chip on the first coin are probably breakage stages, meaning they are the edges of smaller individual breaks that eventuated in what you see on this coin. Just like
Cuds, die chips break away in stages, sometimes leaving their rough edges visible in the newly broken areas.
Both of these are a little uncommon because of their size, but you'd still have a hard time finding a true error collector who would be interested in them at a collectible value - they are just too common for a decent premium.
