Sorry , I notice I made a mistake I must have said the drag force is higher for higher reynold's number and not the Cd . The drag force on sphere is higher than drag force on golf ball for high reynolds number . I am guessing the Cd goes down as it is inversely proportional to the velocity.
I have attached my graphs. This is similar to what others who did the same experiment obtained as well.
missil3,
How are you generating this data, and where did you get your "literature" values for CD? What you say is found in the literature is not correct. Try this site:

It gives a nice explanation, and shows data resulting from well-accepted drag measurements for a sphere at a range of Reynolds numbers.
