1957 D Lincoln Wheat Cent Die Clash And Odd Die Gouge?

Hello Everyone!,
Recently I found this 1957 D Wheat cent. It has a very common die clash under the chin which is a clashing of the T from the word Cent on the reverse. The part that I can't figure out is the raised anomaly under Lincoln's bust.

The anomaly isn't listed on Mad Die Clashes which has me leaning toward a die gouge but it's unlike most die gouges I've seen before. The only die gouges I've run into that are this thick are usually caused by Feeder Finger Damage but that occurs on the reverse of wheat cents. It could be a clash of the B from pluribus but I can't make out enough to be sure.

I took pictures from a few different angles.

Any thoughts?
