The grade is a bit deceiving. The low numbers grade EX/MT+ with many NM and a few better examples. The semi high numbers avg EX again with a significant amount better than that and still with a few NM. The high numbers only avg VG/EX+ pulling down the overall average. The highs top out at EX/MT and there are a few as low as VG but most are in the VG/EX=EX range. A big issue throughout the set is typical centering problems.
