According to Golf.com:
Unlike for the Masters, when Cobra released 1,800 green AMP Cell drivers, they’re cutting back the quantity for the Open. This time, they’re releasing just 600 AMP Cell Pro drivers. (The change makes sense, since the non-“Pro” AMP Cell already comes in blue.) It’ll cost you, too: Cobra suggests a $499 retail, or about $100 more than the non-commemorative club.
Club comes with the same MyFly adjustable hosel and patented SmartPad technology.
The very patriotic club goes on sale June 1st. “Get one while supplies last,” says Uncle Sam with his finger pointing at you!
