Wayne Gretzky will go down in history as one of the greatest NHL players of all time. The hockey legend played for twenty seasons for four different teams, including the LA Kings, between 1979 and 1999.

Gretzky has won four Stanley Cups over the course of his career and his name is famous among NHL fans, regardless of whether his team has him as center/team captain. As a result, the memory of this superstar costs a lot of money. A signed Wayne Gretzky jersey from his Kings days costs US$ 2,500 on the official NHL website.
