Possible mint errors?

[u/BullishMove]

I found both standard german coins in circulation, but something looks weird to me.
2004A: Mintmark seems completely filled and the first zero looks like they tried another font.
2002D: another first-zero-error in my pov.

I don‘t expect a premium on this, just wondering what I‘ve found.

Are these mint errors or post mint errors from circulation?

First one is a grease strike , second one a die-chip. Both small errors , not worth above face or super rare. Still nice finds however.

How can the grease strike form that pattern?
