This 1972-D was from some AU/BU coins I got and at first the cent looked normal but on the reverse I noticed what looked to be the outline of the Monticello dome from a Jefferson Nickle and then I noticed stray marks here and there, on the left there are die trails going E-W and N-S, as well as in the columns and large obliterated areas where the steps and column header should be. On the obverse I noticed the "i" in LIBERTY was split, the "D" had raised areas in the corners as did the "72". The obverse shows the coin is in great condition otherwise so I was wondering if the reverse was a die clash or strike through?
