What is considered the post-war era in hockey card collecting began with the 1951-52 Parkhurst series. With that set, yearly production of hockey cards has gone unbroken to this day. Before the Parkies set, hockey cards were produced on an irregular basis and the last major set came out over a decade before.

Despite the attention given to the 1979-80 O-Pee-Chee rookie card of Wayne Gretzky, there are three cards that have been produced in the post-war era that are fundamentally more valuable. The trifecta of hockey cards consists of the rookie cards of three of the greatest hockey players in National Hockey League history. All three cards are valued by Beckett Hockey Monthly at up to $3000.
