MWTim,
I think you're on the right track. T206 reprints, in addition to often possessing the wrong font styles, also exhibit the following problems:
1. A thicker stock than the originals
2. A smooth, glossy surface
3. Cropped inner images
Generally speaking, authentic T206s have a slightly irregular, somewhat porous surface and little or no gloss. They are also quite pliable or easy to bend...unlike the reprints which can often be somewhat more rigid in construction.
If you have a question on a particular card, post an image of it here and you'll receive some well-educated, expert vintage opinions and analysis.
