‘X-Men’ #1
In 2012, a near mint condition copy of “X-Men” #1 sold for $454,100. This book, the original debut issue of the titular mutant superhero team, has long been a sought-after collector’s item for those with too much disposable income. As with many books from the 1960s, “X-Men” #1 isn’t quite as rare and valuable as pre-war comics, but that doesn’t mean it isn’t in high demand.
