I'm a variety collector, meaning I collect coins with repunched mint marks, double dies, repunched dates, ect....
I can see on the obverse of the coin on the caption "In God We Trust a sunkin in area at 11:00 to 12:00, I don't see any doublinig on the letters from viewing your scan, if there is the slightest bit of doubling on the letters it is considered "machine doubling". The coin looks cleaner than the other, if you had a close up photo, more so, than the one shown, there may be more to signify what you see. 1989, to my knowledge didn't produce any varieties...there is always the 1st
Upon viewing it closer I do see an indication of a line just below Lincoln's beard, and on the left side of his back, this could be a die crack, where the die that punched the coin had a crack in it and when the pressure of the die strck the coin the metal forced itself in the crack, thus producing the hairline you see on some coinage, some can be very noticable to the point that it can become a variety, such is the new Jefferson nickle from 2007-2008 series of jefferson nickles that produced a Die Crack through the back of the bison, which looked like a spear, I believe ANAC, a grading service names this variety "Speared Bison"...value...In MS68 condition...@ $350 - $450...Not bad, considering the 1995 Lincoln Double Die is going for about $125 - $250 in a Mint State condition...
Best bet it have a coin dealer check it out or get post close up photos bud!
