I don't see any clashes, although they are very common in the memorial bays. I do see some plating striations.
If you're referring to the horizontal line between the 3rd & 4th columns from the left, I don't think that is a clash. I have about 225 - 1980 Lincolns with a "Y" clash which is between the 2nd & 3rd columns from the left. It is from LIBERTY on the obverse and is inverted. If there were a horizontal clash, it would have to come from the "T" in LIBERTY, but it would be to the left of the "Y". Chris
