Hi-
The "Catching a Hot One" and the "Close Decision" are fairly common ca 1910 postcards that sell for under 10.00 most of the time. The Hershey Park one is also fairly common (about 10 dollars). The Wagner photo is cool but it appears to be from his later coaching days. I'd guess it would be about 40.00 but could go for more. The "Sports at the Station" is another common postcard (about 10.00). The Henrich is a premium (possibly Goudey or Butterfinger) and it will be easier to identify with measurements. I am sure others will provide more accurate information but at least this will give you a start.
