PSA and BGS produce population reports that shows how many cards they have graded at certain grades. My question is how accurate can these reports be? Are they even worth looking at? I see a lot of people either bust cards out of slabs because they do not like graded cards or they send graded cards in to be crossed over from one slab to another. How do the grading company's update their population reports?
