I never thought I would ever see a fake Emmitt rookie and boy was I wrong.  I recently purchase a 1990 supplemental 101T rookie graded by capitol gem mint 10 only to find out it was a fake.  If I wouldnt have already had a PSA NMMT8 to compare it to I would have prob never know.  Look for the dark blue coloring on the top of the card to be a little lighter in color and the fake seemed to be a slight bit larger.  also some of the lettering font was smaller in size. You must look closely and without the aid of a real one to compare it to it is hard. Also on the top of the fake the 4 white lines are slightly higher than the SCORE wich on the real one line up perfect. and on the back check the national football symbol because it may appear blury and hard to make out. But most of all the lines and color on the back are a great givaway appearing thinner and lighter in color than the real one. I hope this is helpful for you and damn those fake makers!!
