Congratulations.
I'm not a fan of the Maiden pin (like their music, don't like the pin), LZ is boring imo, Avengers and Deadpool isn't my type of theme (really bored of all superhero movies/pins). That leaves only black knight, so yes that would be my pick if it were to keep at home.
I would probably pick DP or Maiden and sell it for cash as both are highly sought after titles. Then I would have bought 2-3 classic 90s pins for the money
