Disney just announced that Moon Knight will be joining the MCU in the upcoming Disney+ streaming service as a new show.
This will likely cause a new demand in early Moon Knight appearances and issues.
Werewolf by Night #32 is Moon Knights first appearance which out of reach for most collectors. Debuting in 1975, Moon Knight has come a long way since his debut, starting out as an antagonist.
Moon Knight made his first solo appearance and primary story in Marvel Spotlight #28. This is still within reach for most collectors. However, these were one off books until Moon Knight got his own self titled book in 1980.
Moon Knight #1 will likely be the most sought after book and can still be found in or around the $100 to $200 range. That might now change after the news has hit with Moon Knight getting his own streaming show.
