Guys--what can these mark be???

@Diogenes Diaz, have you ever watched a video of the minting process? Note how rough the coins are treated and allowed to fall on each other with force. The fact that you are seeing three marks in a "straight line" is due to the shape of the coin, and those marks can be identical and all different locations on the coin. Not a mint error, but simply part of the minting process.

@Diogenes Diaz here is a close up of a 1902-o Morgan. You can see where another coin has rolled up her cheek before being compressed into the metal just above her eye

 

this did it in every case. take two new quarters stand one on end on top of the other and smack it with a hammer, you will get a similar result.

 

Keep in mind, it could have been caused by a Dime too .. or a non-US coin.

Or if it was in, at any time since it's minting, a bag (like a vending machine) it could even been hit by a Half Dollar. Who knows right?

What *you* could do to experiment,
is take 2 quarters.
Take 1 quarter and with increasing strike weight, find out how much effort it takes for a quarter to impose a mark on another quarter.

Then think of the scenarios (both from the mint, from coin processors (Brinks, etc), from vending machines, from people and their purses, coin jars (what happens when someone drops a coin jar - blueprint and document a coin jar being dropped from various heights and blueprint each and every coin in every type of height scenario for each test), et all .. that can meet those specifications of when marks first appear and various other hit imprints.

Of course, then you have to also include non-coin hits. Such as when the mint has cellophane packages and coins get struck with longer "reeded" gear like scenarios. And of course anywhere someone could accidentally drop coinage into *something* .... I'll leave it up to you to think of all the *somethings* that could happen.

Don't disspell "theories" until you test them yourself.

here's an interesting reed ... https://www.cointalk.com/threads/1976-mint-set-with-damaged-penny-inside.282199/#post-2487355

I did that and what amaze me was that I did more damage to coin I was sticking and minimal on the coin been struck--if this happened in the bag then they would all look different?,--But it's always in a straight line
