  • Giant Size X-Men #1 and Hulk #181 have reached insane heights that are many multiples of where they were just a few years ago.
  • With the whole market slowly slightly this week (perhaps the stimulus checks finally ran out) collectors have moved back to the granddaddy of X-Men books.
  • This week we saw a 4.0 copy change hands at $10,100 (up from a previous high of $7,395).
  • And a 0.5 copy hit $2,750 (up from $2,300).
  • Interest is building ferociously for X-Men keys in anticipation of their entry into the MCU.
  • The run up of GSX 1 and Hulk 181 has made lower and mid grade copies of this book seem cheap in comparison.
