1964 Quarter on a Nickel Planchet. Are these lines from improper cleaning, flow lines, or die polishing (abraded die) lines?
If they're from the die they're raised. That's what you need to determine, whether the lines are raised, to answer your question.
There is definitely die polish. For example, the raised lines under the nose. There are probably hairlines also but when holding a coin in one position in the light or imaging it in that way make it impossible to see certain hairlines - even with magnification.
Not necessary, don't waste the money on postage. Now that you see the raised lines under the nose, look for tiny hairlines INTO the coin by tipping and rotating it at the same time.
Not necessarily always true. Post strike scratches and hairlines create both raised lines and incuse lines. And of course so do die polish lines. But they are different in nature than scratches and hairlines. As to the OP's question, yeah the coin has some die polish lines on it. But it has some post strike scratches and hairlines on it too. There's even some on the bust.
GDJMSP, posted: "Not necessarily always true. Post strike scratches and hairlines create both raised lines and incuse lines. And of course so do die polish lines.

ANY TYPE, ANY SEVERITY, and ANY LENGTH of post strike mark on a coin WILL BE INTO ITS SURFACE and not raised above it. The only exception I can possibly think of happens when someone takes a knife and gouges a scratch at an angle into the coin. This produces a raised surface next to the furrow. Ignorant folks these damaged coins were struck with a "cancelled die!" TRUE: As to the OP's question, yeah the coin has some die polish lines on it. But it has some post strike scratches and hairlines on it too. There's even some on the bust.
I'm sorry but it is true. Any scratch, any hairline, they all displace metal. And that displaced metal doesn't just magically disappear, it has to go someplace. And the someplace it goes is into a raised line right beside the incuse line.
I agree. It's the equivalent of running your finger on a clay object (unhardened, of course). Creating the depression means the clay in that area has to go somewhere, thus it displaces and raises along the outer perimeter.
Well it didn't work. Good Morning. It is a bad day when I come to coin talk and get no alerts. I expected to get a good discussion going and raise the old guy from the dead. I do not teach that scratches appear as raised lines on a coin for the simple reason that 98% of the time they don't appear as raised lines that you can see. That's why I used the commonly seen deep angular & intentional scratch (fake cancelled die) that DOES APPEAR raised. Now. If we look at a hairline at 400X it will have raised sides. If wee look at a scratch at 100+X it will have raised sides. Add a slight amount of circulation and the "sides" are gone. Large deep scratched will have raised sides until they are worn down but there is no way a person with knowledge will mistake one of these marks for die polish! One hint: Very often the end of a scratch will have a raised "burr" at the furthest tip from where it started from "displaced metal" that is visible.
Oh don't worry Mike. Your wife always makes sure "I'm awakened" when somebody is needed to keep an eye on you.
She's been acting very suspicious. Asking me a lot about you. I've also noticed the mileage on her "fun" transportation (yellow Beetle convertible) is going through the roof!
Don't worry Mike. She's just wanting to make sure that at your age - you can still remember things. So she enlists the aid of friends to help out with things like that
