The "lines" are from some sort of contaminate, that was already on the sheet of metal that the planchets were cut out of. These contaminates may have been on the roller and spread out evenly, like you see on both sides. After being plated with copper, these contaminates were trapped and over time raised up. As for LIBERTY and the date, they look normal to me.

Correct. Rolling lines. These are actually on the planchet, and not on the die:

Note the unstruck area? Then note you can still see them after the strike, but not as strong.

looks like parallel lines indicative of roller marks from dirty rollers which press planchet metal to their desired thickness. Some mistakingly think they are 'improper alloy mix' errors which are different ('woody') https://www.error-ref.com/improper-alloy-mix/

"roller marks" refers to marks left when rolling out the stock from which blanks are punched. This effect is quite common in copper-alloy cents from the late 1970s and early 1980s.

Not sure. With older coins like morgans, the roller marks added no extra value to a coin and if extreme enough can actually lower the grade of the coin a point or two and lower the value of the coin. Improper alloy mixes found on older coins and Lincoln cents prior to 83 do have added value. A woodie is an improper alloy mix for example. Roller marks on Lincoln cents are found more commonly in the 70s and 80s (78-82 Lincoln cents and nickels had lots of 'narrow striped cents') but also have been turning up looking more like yours on the 82 and later zinc cents. Because of that, it may be worthwhile to hold onto to have it looked at later by someone with far more experience, and this is a nice example. I have not looked into any sales or valuations at this time on the modern common ones such as 78-82 or a zinc one like yours. Ill just assume for now that the right collector might buy while others would have no interest and put no value on them.
