Simple answer.. If it has a Wheat Back it is a 1957.. If it has a Memorial Building on the Back it will be a 1959. The Reverse design changed in 1959. It looks like a 1959 that took a nice hit. Post Mint Damage.
I know nothing about post mint damage, but how would a coin take a hit that turned a nine like the first one into the nine we see here at the end, without any sign of trauma to the rest of the coin? The back of the 9 has been straightened and moved over - which surely isn't possible with brute force. Perhaps in Photoshop, but not in reality.
Copper is a relatively soft metal. The numbers and letters are raised, and easily moved when struck with a small amount of force. Something can strike just that area of the coin, affect the 9 and nothing else.
Yes in reality.. That's what occurred. I've seen many examples over the years. Not a Photoshop picture. Any damage wil wear down over the years.
@John Conduitt This website explains different forms of post mint damage including the slanted numeral issue. http://lincolncentsonline.com/pmd.html
Copper is soft and easily bent or moved, especially on a copper cent. An egg shell is hard until it is struck with something a little harder. Then is crumbles.
Thank you for all your input. It is the memorial building. I thought there were some errors out there however, of 1957 pennies with this reverse?
No, there are no known examples of a Memorial reverse on a 1957 cent. There is a controversial 1959-D with a wheat reverse. http://www.lincolncentresource.com/Controversial/Cents.html
Thank you for your feedback. Why would the top of the nine be straight on the top and the curved part look completely different from the other? I also thought that some of the 1957’s were accidentally minted with the Memorial building reverse. Oh okay! ☹️ Thanks
If you are interested in Lincoln cents here are a few good reference sites. Read up on the minting process.

Thank you! Question? There has to be errors out there that are unknown and found. Is there a way to get your error verified? I live in a small town. I mean a new error can be found right? Just curious for the future. Even if it’s not on the list.
