I have been approached to purchase a used set of AP2's but they do not indicate 710 or 712 which is typically on the hosel. Each club has a serial # etched into it (640UX) but I'm having trouble finding which year they are from. They're looking to get $300 (3-PW) and each club is in pretty decent shape but I'm just looking to date the club, are they a 2010 model or something older? They have Dynamic Gold steel shafts and the grooves are in good shape showing little wear. With all the fakes out there I was looking to verify the serial # but I have no way to decode it. Any input would be greatly appreciated!
