This is an official 2004 Masters flag from Phil Mickelson's historic first Major Championship victory. The 2004 Masters flag is perhaps the most coveted of the dated Masters flags that began in 1999. Flag collecting was booming, but apparently Augusta National did not get the memo. 2004 Masters flags sold out during the practice rounds - meaning not a single flag was available to anyone who attended the Thursday to Sunday tournament days. When Phil Mickelson won, these coveted flags shot up in value overnight and have been highly desired by collectors and autograph chasers ever since.
