What they said above, but it also appears to be very slightly off-centered, but not to a degree that would increase value. Sorry. Jim
86 Lincolns have always carried a hgher price than most other Lincolns of the era. That one is stained from the environment. Lokk for one nearer this condition.
Appears it is stained from either laying in an acidic liquid, or being sprayed with one. ED, environmental damage and NAV, no added value. Note: could have been a urinal coin, so wash your hands thoroughly.
