T206CollectorFour "high dollar" T206 cards at a typical estate sale are almost certainly reprints. Especially if we are talking about Wagner, Magie, Plank and Cobb. You would need to show us scans for us to be sure.
The easiest way to spot a standard reprint is the font. Is the lettering of the players' names brown (as it should be) or black (as most reprints are)? Take a look at the gallery at T206 museum and make your own comparisons. If you've never owned a real T206 card before, it would be very hard to be able immediately to discern a fake without laying a fake down next to an authentic one.
