Your coin is a 1960-D Small date LMC
(Lincoln-Memorial-Cent) On the curve on the '6' on the date there is a mark that all 1960 Small date cents have.
An engraving was done on the master die leaving this area affected on all small date cents.
The areas above the motto (IN_GOD_WE_TRUST) is showing die wear towards the rim at the top of each of these devices. This is call die wear. This happens after several hundreds of thousands of coins are struck by the dies.
The lines above the date are called die scratches. They can flow in any direction or in different directions. They are left over after a die is polished because of a die clash or other die event they are trying to cover up. This reduces the fields a little more each time it is done. The lines can appear to flow behind the devices as the fields are the outside part of the die. So the scratches flow over the void that creates the raised devices on the coin. The raised devices are deeper into the die.
The lettering and devices are mirrored on the die, because the die is a negative, the coin is a positive. While your coin is in petty nice condition, you might want to save it for your collection. But you can buy BU (Brillian-Uncirculated) cents still rolls. I see no hub doubling (doubled die) on your coin, just die wear and no RPM (Re-Punched-Mint mark) on your coin. So it would be a low premium coin.
