Warning: the more you read, the less you'll want to purchase graded vintage cards for investment purposes. So read up!

But basically: PSA, Beckett, and SGC are all incompetent at some parts of their core job of authenticating and grading cards and autographs. A bunch of auctionhouses and trimmers either A) took advantage of that or B) conspired with the grading companies to pump up the value of their cards through fraud. SGC used to have a Grade Guarantee where they confirmed they stood behind the grades they handed out; that went missing from their website quietly a few months ago. PSA still has one, but has told their largest submitters that they have to take back the cards so there's not a run on the PSA bank/grade guarantee and so they can lie about how prevalent fraud is to their shareholders.
