1952 Wheaties counterfeits?
 

I recently started to put together a set of the 60 multi-sport cards that appeared on the back of Wheaties boxes in 1952 - out of the mainstream, manageable size set, not too expensive, don't have to be mint, some nice stars, etc. I looked them up in Lemke's Standard Catalog of Vintage Baseball Cards and found a note saying that they were "extensively counterfeited circa 2002."
Can anyone tell me how to distinguish the counterfeits from the authentic cards? Different card stock? Glossy finish?

Some ancient Forum threads on the subject:

At that time, I tried to find the source of Lemke's information, but could not. Maybe another member would have it.

I stay away from the type pictured on the right.

Not any help but I have Bobs Sportscard Counterfeit Detector 2nd edition from 1993 and they are not listed in it. I highly recommend grabbing one for the great info they have on spotting counterfeits.

Thanks for pointing me to those threads. Good discussion of the topic.
