How did this error occur in the process of minting?

Got this 1939 Washington quarter.. wondering what caused this swath across his face from under his eyes to the top of his lip and swept back into his hair. It's been bugging me for weeks I can't quite figure it out. It's completely smooth (gloved finger of course).
I think it's neat. I imagine it detracts from value. Metal gets rolled out and has a big scuff across it and then gets punched..?
Cheers and many thanks!

Two coins slid against each other under pressure?
counting machine rub
That probably happened post minting...not an error.

That is PMD..... not from the minting process. Cheers, RickO
yeah.
or maybe someone like me scraped it out of a vending machine (although I never literally scraped one, I have dug them out of bubble gum machines when younger... only time for coinstar now.) or it may have been stuck in a coin slot of another type.
No telling what "ran across" it, but it was more than likely done after it left the mint.

What Rick said. Rubber wheel in a counting machine. The coin got stuck under it when the machine jammed.
As Rick and the Captain said,
it's the rubber wheel in a counting
or rolling machine - when a coin
gets jammed ahead of it, the wheel
still spins, leaving the wipe mark you see
on the coin.
It's a common effect, especially for
out of shape errors.
...and, of course this is not a mint error. I have a prized example in my collection with the black rubber residue still attached to the coin at one end of the "Wheel Mark!"
Oh ok. Good to know. Thanks.
