called "striations". Some believe they come from the mill where they roll the metal to the proper thickness, that the tollers pit the lines on themetal sheet and that the press for whatever the reason doesnt obliterate them. But the counter arguement is the press would flatten it out to smooth with all that pressure. Others believe it comes from a mint worker overzealously polishing the die surface and leaving scratches and not fixing it. In which case the situation would fix itself after some use and smooth it out in the strikes. I dunno and I'm not here to argue unsettled theories. If it's pre-mint planchet issue or some die worker polished a die too hard. If that were the case it would only last a bit and the lines getting smoothed out on the die face and not enough struck to be considered a "die variety". Either way there's no collector market for these type of things though, worth what someone would pay for it. A couple dollars tops likely. It's not something seen as collectable in the hobby by many people at all. Yours has been circulated, you can see obvious signs of wear, but there really isn't any mistaking those lines. Generally someone else after minting wouldn't polish all in one direction from rim to rim and would do circles instead or just certain areas, or use a buffer and it wouldn't be so uniform across the coin. If it were die flow lines they'd all start from the center and radiate outward like a starburst pattern. If you want to see more on this look up and read on these.
