1927 International League Baseball
 

I recently picked up this baseball. The box it came it says that it's a Baseball from the 1927 International League.

This is a little outside my areas of expertise. Is it likely from 1927? As best I can tell, the blue and white stitching dates it to that era.

It's not like it cost an arm and a leg but is there any value in cleaning the crud off the ball or does the dirt add to the value?

Thanks.
