Stop. You’ve entered a realm for which you cannot explain. You’re circling the rabbit hole. Take caution. In the very near future you will shank with your hat off. And at that point young sailor, you will be looking at the grey sky from within the rabbit hole.
You can stamp over it and just make a non descript pattern, you can hammer it out to lessen it, or you can grind it out. Obviously the last two will cause damage to the head and finish that will probably be far worse than the original stamping.
Probably easier to just live with it, or change his name!
Okay I wanted to make some sort of smart ass comment, but I'll resist the urge as it isn't likely to be as funny as what @woodzie264 posted anyway. Here's my advice take video of yourself hitting a ball with your hat on. Then take video hitting the ball without your hat. Take down the line and caddy view. Start a My Swing Thread and post them on this forum.
I feel pretty certain that your hat has very little to do with shanking or not shanking. It's more likely the thing under your hat causing the issue. I'm betting if you have a real shanking problem with your hat, that problem will rear it's head (pun intended) sooner or later without your hat as well.
