What causes these triangle marks on coins? Are they test marks?

I've seen this mark before but I can't find anyone discussing it.

    @Brandonsss Welcome. Your question would be best served by posting pics of the complete coin, obv and rev. Good luck. Peace Roy

    Year?
    Denomination?
    Condition?
    Road kill?
    There must be a reason not to post pics of front and back..... deception?
    So many questions, so few facts.

    Beneath the image it says “ Tagged: John F. Kennedy”, so I’m guessing it’s a half dollar.
    “Deception?” - really? That was uncalled for.

    Coins with reeded edges will make those kind of marks when they hit other coins. ;)

    That’s by far, the most likely answer to the question “What causes these triangle marks on coins?”

    Sorry and no there isn't a reason why I didn't post more pictures. I'm new to this and assumed someone with experience could tell from those marks. The marks are pretty distinct. The location is in the middle of Kennedys face. 1964 and Condition is Good

    Usually, good clear pictures of the whole coin are better than the super magnified ones. With pictures like this it is impossible to see the size and location of the marks or even what kind of coin it is, which are important to identification. Most likely scenario are the reed hits as already mentioned, but just a guess without better pictures.

    Contact marks. Bag marks. Reeding marks. Normally found on larger silver coins such as Morgan dollars.

    I'm thinking that a microscope could make coin collecting much cheaper. If you map the surface of a coin at 100x, you will have dozens of unique photos of all kinds of errors and varieties by buying just a single coin. With a little pareidolia, you can find an S, D, O, CC, and P mintmark on every coin!

    It’s not fair; they stare at a coin for a month under magnification and expect us to see those things in an instant.

    I have a 1921 Peace dollar with similar markings. I assume this is what he is talking about.

    collectors have been using microscopes long before you was born. Thats why older people have alot more knowledge when it comes to errors and etc.

    Thank you for giving me the recognition that I deserve for my knowledge of etc, but you would have to write hard to make that statement any more inaccurate than it is.

    @Brandonsss you might want to work on your reading comprehension. Fraz and others in this thread are trying to help you. You're not making that easy for them.

    There is a thread pinned to the top of this forum that provides links to read for learning about coin collecting. That would be an excellent place for you to spend some time.

    True numismatists RARELY use microscopes. The experts on errors and varieties generally work with 10x loupes or less. There is such a thing as too much magnification.

    I can't see it. Could you blow it up 100x?

    Yes. For example added "S" to 1893 Morgan.

    Wow!!! What's wrong with members who should know better??

    One constant through the years is worry about the Hobby and new participants. The solution to some is sort of misguided: harangue and mock newcomers to this forum.

    Just ridiculous.

    I see members making sincere efforts not to do that—more than before. I mock and I harangue when I see posters abuse the members who strive to teach.
    Brandon is chill, he thinks old people are wise, no one has mocked him, and he knows that we saved him forty dollars submission fee. I contradicted his statement firmly, others advised him firmly. No harm no foul.

    "Frequently" amounting to 1% of coins graded which constitutes "rarely" in my book.
