The other day I posted and that coin ended up being damage. I was told some useful information about the rolled over edges is post mint damage. This coin doesn't have that and most of the features are clear. Dont really know too much about figuring out damage from mint damage. any tips?

Looks like it was runover by a car tire while laying on some hard surface (cement/blacktop). As the damage is "pressed" into the reverse not scraped or hits causing the zinc core to appear.
As far as the lines go - can plated cents show roller lines from the zinc to show through?

Occam's Razor: Is it more likely that a car ran over this penny and caused mechanical damage to the side that was on the rough pavement or that a reverse die which was used to strike the exact same image onto flans bajillions of times was damaged at some point, the mint personnel either didn't notice or didn't care, and not a single coin collector has stumbled upon this mint error in the last 14 years.

I know that I'm being a little unfair as you are still learning what to look for, but my point is that you should try to see these coins from how they were manufactured. This will help you not only when you see something odd, but also help you to discern which types of doubling increase the numismatic value and which ones don't. You should spend some time over at error-ref.com to learn about this stuff.

I'd also recommend spending some time hear reading through old threads in this subforum. Look at coins that others have posted before you and then read through our discussions.

The "doubling" is caused by Die Deterioration.

PMD. Looking for random anomalies on coins and hoping they turn up as something collectable makes a huge number of dead ends and frustration b/c of the literal billions of coins in circulation being used/abused and beat up daily.

Read error-ref like a book.

To escape being fooled by simple damage, a person need, at a minimum, to know the minting and die making processes. :D
