The raised areas that you see on your 57-D cent are due to displaced metal. If you look closely, you’ll see the gouges and digs on the surfaces that correspond with the raised areas. The mintmark also suffered a hit that displaced the copper, which gives the appearance of a RPM, but it isn’t. Copper is relatively soft, and it isn’t hard to push the metal above the minted surface when it’s hit with a sharp object. If you look at it with a 5X-10X loupe and rotate it through the light, the digs will be apparent. I think the technical description of your coin would be “pecked to death by a chicken”
If you’re talking about the Cent, there are no errors on it. First of all, look at the coin as a whole. What do you see? I see a coin that’s been heavily circulated and damaged all over it. Red circles show damage. It’s very possible that the damage was done early on and then the circulation made the raised areas wear down. Even so, yellow arrows point to raised metal. Raised areas means metal was pushed. Inside the mint, when a coin is struck, there is nowhere for the metal to go, so there should be no raised metal. Please take the time to learn the minting process to understand how dies are made. Then you’ll realize everything you see here can’t happen at a mint.

Thank y'all. I will Def try not post any more threads or bother you until i educate myself. I appreciate all.
Posting threads and hearing our responses is part of the education. I gave several suggestions as did others, so please keep posting and stick around. You'll learn a lot.
Fred seemed to indicate that the blob B was a die chip, which is an error. Although not valuable. It would be an error because it happened at the mint, and not after like all the other damage.
Anytime a member here is willing to learn then we are more than willing to help. See the shiny flash across the B and E of LIBERTY that is where a coin scraped the surface of the coin. An easy way that I learned was putting down any coin that was not evident or one that I should look into. I focused on Mint state examples with maybe the slightest amount of circulation. Most of you don't understand the blessing it may be to your education in this hobby, especially errors and Variety's. A box of uncirculated rolls of new coinage, will quickly learn someone of the way a coin should look. When you get change that is new, buy another dollars worth. Unless the error is blatant, You will not find an error or variety unless you first know how they look new (MS) Good luck Nick, I hope you understand that there are no stupid questions. Unless repetitive.
Also circle every device on the coin (in blue) that has a white flash. The flash is wear and circulation damage.
