1978 Strike through to grade or not to grade 1 1

Curious to see if anyone thinks i should sent this in and have graded or sell raw.

Sorry, but it isn't an error.  It looks like your coin suffered some type of chemical exposure/damage after it left the mint.

Agreed. Just damage. It may have been in a tumbler at some point with all that stippling. Metal detector finds get tumbled with rocks or other media that has a similar effect. Could just be a corrosive chemical. Regardless of cause it didn’t happen at the mint.

Acid.
