Larry Frisch issued a complete reprint set years back, but the backs are snow white and say 'reprint.' Your backs are off white/toned like the originals.

For the original cards, the fronts, and only the fronts, of the cardstock was coated in a smooth white substance before printing. This was to make the colors look sharp and because there were no white inks used (no ink = white). The front of the cardstock was essentially enameled before printing, while the backs were not (au natural). The backs have just monotone text, so back enameling needed. In fact, paper coated in a white substance is called 'enameled paper.' They did this front-only enameling for many original vintage card issues, including the T206s and vintage Topps cards. So the front white borders (where there is no ink) and the backs on the originals should have different tones, feel and gloss. The front should be smooth white, while the back should have a more matte, natural cardstock feel.

If you look at any original T206 or 1950s-70s Topps regular-isse card, you'll see that the fronts have a different gloss and feel to the backs. That's because the fronts only were enameled before printing. Comparing the front to back gloss/texture, and the backs having a different natural cardstock texture, is one of the bet ways to identify an original.
