Sammelwerk Trading Card - JESSE OWENS HELEN STEPHENS

So I have about 200-300 of these Sammelwerk cards. From what I understand they came in cigarette packs during the 1930's in Germany. The majority of mine are from two different sets. One is Hitler propeganda, 100's of glorious photos of Hitler and Nazis. The second set if of the 1936 Summer Olympics.

From what I can see on that auction site. The ones of Jesse Owens are the most collectible. Here is one of those. These cards are interesting and I am looking for someone who knows about them. Are there specific cards I should look for. There are hundreds of them. I wish there was a price guide for these! Okay, thanks!!!
