Since becoming the only NFL franchise in the Pacific Northwest region of the U.S. in 1976, the Seattle Seahawks have established deep roots in the area and have gathered a vast number of dedicated fans. The Seahawks entered the league in 1976 as an expansion franchise, and though considered as a young NFL franchise, the team has experienced an incredible amount of success. The Seahawks’ fan base is one of the loudest in the NFL, and on two separate occasions in 2013, fans at CenturyLink Field have set a Guinness World Record for loudest crowd noise at a sporting event. Because the Seahawks are the reigning NFL Champions, their memorabilia has reached an all-time high in value. All Seattle Seahawks products retain value and the time to invest is now while the team is atop the NFL.
