$100 for the complete set, I had just spoke to a rob griffin at ping. He had given me some information on the irons. He said 8 of the 9 clubs that don't have a serial number could possibly have been owned by a pro, because they don't come out of the shop without having a serial number. However the 6 iron does have a serial number of 868247 meaning the owner could have lost a 6 iron and bought another off ebay and such but the serial specs said the iron was orange dot, c3 swing height, and cut 3/4 shorter so it is alost the same size as the 7 iron, however it's showing blue dot. Nice customer service by the way for Ping.
