Welcome to the site! That's a very common occurrence from that era so you'll definitely see those from time-to-time--sheets were loaded in incorrectly and got the wrong front/back. There are collectors who enjoy chasing stuff like that, but most of the time they're just chalked up to human error and ignored.
You didn't ask but you won't see that kind of thing listed here because it's considered a misprint, and due to the possible endless combinations of wrong fronts/backs, missing foil/misfoils, color variations, and similar stuff, the database would get out of hand in a hurry.
So you have yourself something interesting, if not rare, that you can either keep or send to someone who collects errors or either of those players.
