I disagree. The sheer numbers of cards would tend to suggest that is an overstatement. I would agree that a large % of the allegedly high grade prewar cards have been altered. Those of us who've been around collecting for 40+ years know what was out there on average in the cheap days and as compared to what is out there now, the ratio of high grade to all grades has increased over time. I do not think that is the result of 'finds' (though there have been some, e.g., the Black Swamp), but for sets like T206 and 1933 Goudey, no, sorry, those cards have been worked.
