Tony, an easy way to spot a reprint Goudey is to look at the bottom red border, it
should NOT match up perfectly at the ends with the rest of border. Sometimes this is hard to see on a scan but all the cards in the auction in question failed miserably. Other things to look for are picture cropping, white border, fuzzy/faded picture (like the Ruth in this auction), back side paper loss where the world reprint might appear, etc.etc.etc... Here are two examples of a real and fake 1933 Goudey Gehrig card (and what to look for):

The best way to tell the difference between a known Goudey reprint and a original is to handle a couple dozen real Goudey's. Feel them, caress them, admire them, smell them, and on a cold winters day snuggle-up to them. Once you do that, you will be able to spot the difference. Now run away young Jedi, and use this knowledge for the good of mankind.
Lovely Day...
