As a fan returning to collecting for the first time since the 80s, and who had no idea at first about the AFA or indeed U grading, this guide has proved incredibly informative and invaluable.
I'll echo the majority of responses: why would you do it? I suspect all future collectors will look back on this period as a savage and sad time where greed got the better of sense.
I for one will not be going down the grading route, U or otherwise. Has this practice abated somewhat in the last couple of years?
