It doesn't get much rarer than this.
It's one thing to have a unopened pack of Baseball cards from 1954, but to have one with a Jackie Robinson showing if quite another thing. Here, in Memory Lane's current auction is a 1954 Topps Baseball Penny Wax Pack graded by PSA. Unfortunately, it's a bit tough to see the Robinson.
Here is a video with the auction house introducing the unopened pack.
