I think one of the things is that grading is not as accepted in the AFL collecting, as it is in the states with basketball,baseball,football.
not saying it wont in the future. Maybe it will, maybe it wont?
- I have a range of baseball cards slabbed in PSA, but no afl graded at all
-as for aus grading compared to u.s .. no idea, but some others on the board could answer that for you
if I was to grade, I would be more inclined to grade older scanlens, then modern select.
