I'm just wondering what these lines are on this penny this one's look funny because of the way they go through the day can anybody explain? I know this isn't super rare or any kind of error I'm just curious for my own knowledge.

Hairs on your arm?

The date seems to have a die crack.

Best not to hold coins that way. The oils in your skin can cause tarnish/corrosion.
