1976 Ike Dollar 0

It’s what’s not what I think it is, it’s also struck off center.

   The depressed area and surrounding raised metal in the "S" are clearly from a nick or gouge.  The coin isn't "off center" either.  The obverse die was slightly misaligned, meaning that it wasn't mounted in the press so as to be perfectly perpendicular to the coins it was striking. Coins struck from misaligned dies are quite common and generally command no premium. They are considered to be examples of poor quality control rather than mint errors.  An off-center strike would be off center on both sides of the coin.  Here are NGC photos of a 1988-D Kennedy half dollar that was struck about 80% off center: While this is a particularly dramatic example, the two sides would always be about equally off center.
