Rolled or ground?

Can you tell from the picture if this is rolled or ground?
Attachment 21610

Do you have a better close up of the threads?
Rolled screws tend to have a groove in between the threads, whereas ground screws don't.
In the pic, left is rolled, right is ground.

I'll grab a better pic and post it shortly, but thanks that makes it easy to ID.

I'm pretty sure it's ground looking at those photo's.
