Mint Errors ?

Got these in change today. You can barely see the LIBERTY on the penny's obverse. Are these errors from the mint? Thanks.

    They are from the US Mint, but they are not errors.

    Welcome to the forum! :)

    Everything you are showing is post mint damage. (PMD) :/

    @Unit91... Welcome aboard. Sorry to say, as above, those coins are PMD... not mint errors. Cheers, RickO

    Just imagine that the US Mint has two dies that when struck together with a planchet in between the dies, a coin is formed.

    Picture this in your head.

    Anything that happens past that point to the coin is damage.

    Now, when you see a coin that you may think is an error coin, go into your head where the imaginary US Mint is and explain how this happened when struck?

    Last one is environmental damage along with post mint damage.

    I don't know what video you watched but there are some good ones on the US Mint site. ;)

    May I ask how to know the difference? Is there a publication? Thank you.

    "May I ask how to know the difference?"

    Learn about the minting process, and there are publications about it.
    There isn't publications on different types of PMD because there is thousands of ways to damage a coin.

    Thanks to you all very much! I watched a video but it didn't show the entire process.

    Somebody seems to have somehow scraped off the design on the quarter's reverse, maybe with a Dremel or something.
    The cent looks like it got scraped up on both sides, likely in a parking lot or other asphalt/cement area.

    The quarter is interesting in that a certain mint error, called a "die cud", could make a coin look similar. However, your quarter was damaged and part of it was rubbed off. Here is a genuine die cud on a cent:

    It would be caused by the coin's die breaking and a piece falling off. Here are some pictures of dies with die cuds:

    (The dies pictured a from a private mint, not the U.S. mint. They were used to make tokens.)
