Looks good to me,nice find!!still haven't found an error truly special a capped die would be awesome!!!.
Now, of course, the finder is asking me if he should get it graded and slabbed. My impression is no. Anyone else...
Having it graded and slabbed always comes down to a question I ask myself. Why? So I can get more if I sell it? So it is protected? So I can win a bet on the grade? I think your friend needs to ask themselves those questions after they find out how much it would cost them to have it done.
