Those are different lifts of the pours when it was cast. If you look carefully you will see they are not level or uniform thicknesses. I really don't understand all the suspicions that there is something hidden inside.
Or that it is two pieces fused together.
So in the names jesse is spelled with an i which is wrong. Frank is spelled with a backwards n which is not right either. Put those two letters together and it gives you the word IN! Maybe there is something inside. Probably not but ya never know.View attachment 1792551
